Circuits
Overachieving and under-appreciated, circuits are the foundation that our technological society is built on. Now's your chance to find out not only how they work, but why. Questions regarding the physics behind voltage, resistance, capacitance, inductance, transistors, LEDs, switches, and power supplies; and how they're used to create analog and digital circuits, should be directed here.

Has pins on opposite sides of the circuit board that connect together to form one set of contacts?
SIMM (single inline memory module )
How many electric paths do you have in a series circuit?
Depending on what type of circuit your talking about.If the circuit is in parallel,series/parallel,then your talking as many loads that there are on the circuit.However if your dealing with the basic series,then there are the going out and coming back in. so two.and that's not including the ground path.
ANSWER :Only one path and there is from a positive to a less positive potential
What are the advantages and disadvantages of capacitors?
If you're talking about a capacitor for car audio related use, then I have the answer for you! :)
There is a lot of confusion in the industry about what the purpose of these are so I will get straight to the point.
Advantages: Capacitors reduce interference in the signal to your amplifiers therefore making your system cleaner. SQ cars use these typically. They can help with dimming lights but should be considered after an alternator and AGM battery are added as these are your best choices first.
Disadvantages: Capacitors actually reduce voltage slightly and interfere with direct current flow. As fast as they discharge they are almost useless in providing anything for long drawn out bass notes associated with rap etc.
*Note: Don't add one if you're already trying to consume more power than your charging system can produce. People use capacitors as a "band-aid"
to try and fix a bigger problem.
How does a circuit breaker protect you?
A circuit breaker limits the amps that a circuit can carry. If the amperage draw on a circuit exceeds that limit, the circuit breaker turns off the circuit.
If the current through a wire exceeds the rated amperage, the wire will overheat and eventually cause a fire, or at a minimum, destroy the wire behind inside the wall.
Obviously, people don't want a house fire caused by an electrical overload, so circuit breakers are used to prevent damage and potential loss of life.
Which conditions refers to a reduced voltage level of AC power that lasts for a period of time?
The name for this is a brown-out.
How much voltage is needed to hurt or kill people?
It is the path of the electric current through the body that will kill, not exactly the voltage. If the electricity go through the heart, it will have a higher chance of killing that person. Generally 100-300 voltage can shock the heart to defrillation. Higher voltage will probably stop the heart, and the heart could be burnt from the high voltage too. If the body is NOT earthed, the body could probably survive.
ENIAC was developed in what year?
1944 Construction on it started in 1943 and it was unveiled in 1946. Hope this helps!
What are the 2 main electrical circuits?
The two basic types of circuits are series and parallel circuits.
What type of data does a CMOS chips hold?
date and time is one of them it also stores settings about drivers on the computer
What impact did the integrated circuit have on society?
Mainly overwhelming reduction in computer size, phenomenal increase in computer speed, reduced power consumption, reduced heat dissipation and an astonishing increase in overall computing power. Other than that, there haven't been many advantages to integrated circuits.
What four things are needed to complete an electric circuit?
The four elements of a complete (electrical) circuit: 1)A source of input (power supply) 2)A means of conductivity (usually wire) 3)A means by which to open and close the circuit (a switch) 4)An output device (motor, light bulb, etc)
How does a magnitude comparator work?
magnitude comparator is a logic circuit used to compare the two binary numbers in order to determine the relationship between those quantities.
How to get the CMOS battery out of a Acer travelmate 6292?
Your best bet is to remove all system batteries, and the power cord, then remove the CMOS battery, and wait like at least 20 minutes. Then put the CMOS battery back in, and then the system batteries, and power cord. You will have to set the clock, and boot order, as well as any system specific settings.
I got that you have to remove the cmos battery. My Question is about just that. what comes off the back first. I have a Acer Travel Mate 6460. I am not opposed to removing the back cover and getting to the Cmos Battery. I just need to kn ow the process. I don't want to cripple the machine for ever being ignorant. I need instructions with a couple pictures or plans so I do it correctly. Do you have any plans or scematics for the Acers?

How do you remove thermal paste?
Usually you should use an alcoholic wipe (try your first aid kit), but a baby/wet wipe and kitchen role to dry would work.
One possible risk caused by mains voltages?
-- proliferation of electrical and electronic devices in the home, leading to a
surprising and shocking bill at the end of the month;
-- excessive current flowing in an inadequately sized conductor, leading to
overheating and possible fire;
-- grave mortal danger to a human person, caused by placing his body in-circuit
between the mains supply and a grounded point.
Note that none of these risks is "caused by" the mains voltage. Any risk is due
to careless and inattentive handling of the mains supply by people responsible
for its proper use. In this respect, mains voltage is no more risky than a car,
a bottle of sleep aid tablets, a pistol, or a discarded banana peel.
What does a battery do in a circuit?
It stores electrical energy charge which then provides power to the circuit. Electricity is the stream of electrons through a conductive way like a wire. This way is known as a circuit.
Batteries have three sections, an anode (- ), a cathode (+), and the electrolyte. The cathode and anode (the positive and negative sides at either end of a conventional battery) are snared to an electrical circuit.
How do you convert a 240 volt circuit to 110 volt?
By asking this question you are probably not quite ready to take on this particular task. Really, don't do this one yourself. Electricity is far too dangerous to handle if you have not been trained how to do this work. If you use the wrong size and type of cable for the job and/or put just one wire in the wrong place, you risk being killed by electrocution or you could even start a house fire. How to do this job depends entirely on the Wiring Codes or Regulations for the locality (Town/County/State) and on the exact location of the electrical equipment you wish to be installed. If situated anywhere that is subject to water splashes, water spray, dampness or humidity - such as in any room supplied with running water pipes, like a kitchen, laundry room, bathroom, shower room, etc., or in a workshop, or garage (or anywhere outside a building in the open air, such as along an outside wall - or a pool-side area) in many places nowadays it is actually illegal to attempt to do this kind of work unless you are already a licensed electrician. If you get any other answer here, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or even their life. <><><> 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. Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

What parts of the cell are used to connect a electrochemical cell to a circuit?
The nodes of the electrochemical cell are called the electrodes. The Cathode is the + end (of a battery). Negative charge enters through it. The - end is called the anode.
What is the resistance of a fuse bulb?
A lamp has two resistances: a 'hot' resistance (its operating resistance) and its 'cold' resistance (its resistance when switched off), and the hot resistance is significantly higher than its cold resistance.
You can calculate its 'hot' resistance from its rated power and its rated voltage (assuming that it is being supplied at its rated voltage), by manipulating the following equation, to make Rthe subject: P= V2/R
You will, though, have to measure its cold resistance.
Do you use Parallel circuit at homes and schools?
Every outlet in a home or a school is in parallel with every other outlet in the same
home or school, and also very possibly with every outlet in several other buildings
nearby. Every time you plug something into an outlet, you're connecting that thing
in parallel with every other electrical thing that's plugged into any of those others.
What happens if there is a break in a serious circuit?
A break in an electrical circuit will cause the circuit's load to stop operating.
The pressure that pushes the current
Answer from University Physics Ed 11Voltage is the potential Vab of a with respect to b, which equals the work done by the electric force when a unit charge moves from a to b.
1 Volt = 1 joule/column b
