What type of circuits are used in most homes?
a house is a big paralel circuit but it is possable to wire somthing in series in a house like if your refrigerator is on its own circuit it would be a series circuit but its full of more wiring itself. I guess the best answer would be a complex cicuit,
What farad capacitor would you put on a 3 volt DC motor for fastest rpm?
if u want it to go faster u want more current. a capacitor is not going to do anything for u unless your haveing problems getting it to turn
I don't know about the warranty, but the unit will run fine using an extension cord IF you buy one that is heavy-duty. Look for a cord that is 12 gauge or even 10 gauge. If you use a 14, 16, or 18 gauge cord (these may be too small), the unit could be damaged.

Can 240volt or higher be transformed into 12 volt easily?
YES. CHECK CONTROL TRANSFORMERS INSIDE MOTOR STARTER OR MOTOR CONTROL CENTERS IS A GOOD EXAMPLE EVEN UP TO 6 V PILOT LAMP.
Why do you use ' I ' to represent current?
'I' represent current in electrical circuits because it stands for intensity, which is another term for electric current. The symbol 'I' was derived from the French word for current, "intensité." Hence, the letter 'I' has been traditionally used in formulas and equations to represent electric current.
A relay is an electrical device that?
A relay is a device that takes a smaller source of electrical power and using it to manually control a larger source of electrical power. Typically, a low voltage or low current source, which is more easily manageable with control circuits, sends a signal to energize an electromagnetic coil. When the coil is activated, the magnetic field moves a plunger type device which has contacts that serve as a switch for the larger voltage or current device. In essence, the contacts complete the path for the circuit and allows a load to begin to operate using the higher voltage or current that is supplied through the contacts' connections. A good example is a house air conditioning system's condenser unit (the part which contains the compressor and sits outside of the house). The condenser requires 240 Volts Alternating Current (AC). But the thermostat inside the house uses a 24 Volt power source. When it's time to cool the house down, the thermostat on the wall sends 24 Volt signal to the relay in the condenser unit. The 24 volts causes the coil to energize and makes an electrical connection to the 240volts required to power the compressor. The compressor now runs and your house begans to cool off. Once the set temperature is reached, the thermostat discontinues the 24 volt control signal and the 240 Volts is disconnected from the compressor by the relay, thus shutting off the condesor unit. In cars and vehicles, a relay performs the same function, except that the voltage is not 240 Volts AC. It is 12 volts Direct Current (12VDC). It is used in the air conditioning system in much the same way, but is also used to control the blinking of turn signals, the horn, and in some cases headlights. The voltage remains at 12VDC, but large current flow is controlled by small current flow. For example, 12VDC at 10milliamps through the relay could contol the headlights which may require 12VDC at 5 Amps to shine brightly enough to see at night.
How much is 200 watts in degrees?
The answer to this question is more scientific / mathematical then simple, in terms of questions this one refers to kelvin/watts to degrees. the simplest (not always right) answer is 40.83c or 105.5f
the formula is:
degrees = [(W x T) / G] x shc
W = watts
T = time
G = grams
shc = specific heat capacity
This will calculate for degrees centigrade, do a search in google to find the specific heat capacity of what you are calculating for and you will get a better answer
How to wire 4 prong generator plug?
Stop! What...? Don't try to do that...!
Don't make a cable with the intention of plugging a generator into an outlet in your house, it is incredibly dangerous!
Power from your generator will back-feed into the power lines, posing a severe unexpected shock hazard to any line-workers who may be fixing the lines - the very same reason you are wanting to use your generator!
Plug your appliances directly into the outlets on your generator. If you want to power the outlets in your house from the generator you must do it right and install a proper 'generator transfer switch' at the main incoming breaker panel which is situated where the main electricity service cable comes into your house.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.
you probably can't, you need a neutral and a live wire to make a fan work. switches normally only have live wires.
A fuse(s) or circuit breaker(s) is needed in any electrical system (AC or DC). These protection devices react to the amount of heat being produced by electricity passing through wires and/or components. They are used so as to protect wires and components from the extreme heat produced should there be an electrical overload or short circuit. When a short or overload occurs, the amps being drawn spike and this increases the heat produced in the wiring and components. When this occurs, a fuse or circuit breaker reacts almost instantly to stop the flow of electricity in the circuit and thereby stopping heat production. Without PROPERLY-SIZED FUSES OR CIRCUIT BREAKERS, this quick break in the circuit would not be possible, and damage to components and even FIRE could result. If you are having a problem with fuses "blowing" or breakers "tripping," please know that these devices are doing their job! It is important that you NOT replace a fuse or breaker with a higher-rated one. Check the circuit for shorts or overloads. Bare wires touching each other, as well as having too many appliances on a circuit is dangerous and will cause fuses to blow and breakers to trip. The wiring in your home or business is sized for a specific amperage. Increasing the size of protection devices will cause your elecrical system to not be protected adequately. Branch circuits feeding lights and 120 volt recepticles should have only a 15 amp or 20 amp protection device, depending on the wire size. If you cannot locate the overload or short, keep the power to the circuit OFF and contact a qualified electrican.
Why do some people more easily get electrocuted than other people?
Some people have excess of iron in their blood. This would make them more conductive. People who eat alot of dark green vegetables, and red meats get more than people who prefer chicken and rice. For the most part men are more susceptable to shock because they have a lot more iron in their blood. This is because men don't menstruate, and therefore don't have nearly as many red blood cells leaving their system. On CSI they said that having an extreme excess of iron would be accompanied by small testicles, about 1/3 the size. That is totally silly. That has little or no effect compared to the much much bigger issue to do with why some people like men are shocked easier. The plain answer is duuuhh saltwater you sweat and its very salty water an awesome conductor Men typically sweat more then women. And you have what could be called an insulator separating the bare wire or what ever from your iron in your blood your skin!!!!!. Of course with a high enough voltage/amperage even dry skin will break down into carbon and become a conductor just like iron. And the idea that women have less iron then men because they menstruate!!!!! hahahahaha that's terrible you know how little blood comes out and it only happens a couple of days a month, they would have to lose pints and pints of blood to a big difference in iron count. Women dont feel weak like they just gave blood after their period. OK glad i corrected this silliness
Should an electrical outlet box protrude or be recessed relative to the wall?
Are you talking about recepticale boxes that you plug a device into or service panel that the breakers are in?
It depends on what else you are running in the house. Add up your amperage to see if it is more than the 125amp rating. Which should be below 105 amps constant to keep from overheating the main breaker. If you are not running a big central ac system or a electric oven and water heater you should have no problem running the hot tub.
What percentage of electricity in Europe is produced by nuclear power?
- "Europe draws nearly a third of its energy from nuclear power..." http://www.forbes.com/feeds/ap/2008/07/10/ap5200802.html "Only about 30 percent of Europe's electricity is produced by nuclear plants..." http://www.coxwashington.com/hp/content/reporters/stories/2008/02/10/NUCLEAR_EUROPE10_COX.html "Across the 25 EU states, 148 nuclear reactors account for 32 percent of electricity needs..." http://www.terradaily.com/reports/Fossil_Fuel_Crisis_Drives_Europe_To_Nuclear__Green_Energy.html

How was the first battery made?
The first battery was made by Italian scientist Alessandro Volta in 1800. He created the first electric battery, known as the Voltaic pile, by stacking alternating discs of zinc and copper separated by cardboard soaked in saltwater. This setup generated a steady electric current.
Im guessing this is a petrol lawnmower. sounds like the float is not set at the correct level in the carburetor
Does using thicker wire make a electromagnet more powerful?
The wire in a electromagnet is the conductive property transferring power. The thicker the wire the more power transferred to the electromagnet for a exponential amount of power.
Is it safe to plug a surge protector into a surge protector?
Yes, absolutely. It will not hurt a thing but if the one on bottom goes out, the one on top will not be protecting anything. see this article...
http://handydandytips.googlepages.com/howtoprotectyourhomeelectronicsfromlight
Also you can not exceed the amount of amps the outlet provides. Two surge protectors are okay. Don't listen to all of that crap about how surge protectors are so horrible bla bla bla. None of that means anything. If you tried to plug 100 together that is a different story because the outlet would run out of amps.
How do you find resistance when you have current and resistance total?
If you are looking for the resistance of each resistor in either a series circuit or a parallel circuit you must measure the current I and the voltage V for each resistor. Then calculate its resistance using Ohms Law R = V / I where I = current (Amps), V = voltage (Volts) and R= resistance (Ohms).
For 3-phase supplies what are the standard wiring insulation colors?
In mains power generation terminology power is commonly generated at the power station in three separate "phases". The "Hots" ("Live" wires in European parlance) of each of the phases are timed to "lag" each other in wave/cycle terms as follows: the Hot of the first phase is generated at 0o (Zero degrees, which is equivalent to 360o), the Hot of the 2nd phase is timed to lag the Hot of the the first phase by 120o and the Hot of the third phase is timed to lag the Hot of the first phase by 240o. In Europe, where power is generated at 50Hz, the "Hots" (labelled as lines L1, L2 and L3) making up each of the three phases commonly have the colors Brown for L1, Black for L2 and Grey for L3; the Neutral wire is Blue. (These are equivalent to the UK's old wiring regulations for 3-phase supply cable of Red, Yellow and Blue where the Neutral wire was Black.) Perhaps someone else could say what the colors for the Hots are in the US or other countries which use 3-phase power generated at 60Hz? A new question will be asked about this. The number of phases delivered from the street to a building depend on its power usage requirements: an industrial building or site which uses 3-phase power for powerful motors, ovens, etc. must have its electricity delivered as 3-phase power; commercial offices or domestic homes typically only use single-phase lights and appliances, so such homes and offices usually only require 1-phase (single-phase) power to be delivered from the street. Note: For mains power any 1-phase supply is usually obtained by using just one phase of a 3-phase supply that comes in overhead or underground cables from the generating station. The power company typically supplies a given neighborhood with 3-phase power and distributes it as separate 1-phase supplies, one phase per street or group of streets, so that each house in each street gets its 1-phase power.
If the owner requires it, it is usually possible to pay the power company to provide a 3-phase supply into a house or any other type of property, such as an engineering workshop, vehicle repair garage, etc., that may need to have a 3-phase supply to power heavy equipment such as big motors installed in machinery.
Why are neutral and earth wires connected together at the panel?
The quick and dirty answer is that the live wire (or hot/black wire) in a North American supply has a potential of 120V above ground - The voltage you pump out of the hot wire will do what it is meant to do (such as heating a kettle element) and then find the shortest path back to ground which in this case should be the neutral wire since it is directly bonded at a very low resistance path to the ground (your panel earth will probably be connected to your cold water pipe inlet, or to a metal pipe hammered into the ground).
A more complicated question is why do you need a separate ground/earth wire when both of them are connected to the same thing. I will leave that one for someone else :)
