Electrical Wiring

In a parallel circuit, the total amperage increases as the number of bulbs increases because the current has multiple paths to flow through. Each bulb offers a separate path that allows more current to flow. In a parallel circuit, adding more bulbs decreases the total resistance, allowing more current to pass through.

The potato was named by the Spanish conquistadors in the 16th century. They adopted the name "papa" from the indigenous Quechua people of the Andes region, where potatoes were first cultivated.

If you reverse the Live and Neutral, it won't make any difference, as the current flows between these two wires.

However if you connect either the Live or Neutral to Earth, then you'll get a loud bang as the fuse blows and a bright blue flash. If you're lucky. Otherwise you could electrocute yourself, or someone else.

If you don't know which wires go where, leave the work for a Professional.

Electrical pressure, also known as voltage, is measured using a tool called a multimeter. The multimeter is typically set to measure voltage, and the probes are connected to the circuit or component where the voltage is to be measured. The reading displayed on the multimeter indicates the electrical pressure in volts.

Pure distilled water is not a good conductor of electricity. It is the impurities in water (usually salts) that conduct electricity. In fact, the conductivity of a sample of water can be used to measure the concentration of salts in the water sample.

Probably not. The manufacturer has designed this as a three-phase to cut down on the total wattage required to run this kiln. Through the magic of 3-phase the power draw is 57% of what it would be for a single-phase kiln.

There is an item out there called a "phase converter" that lets you run a three phase item off single phase service. I've looked at these before, and they're expensive, noisy and inefficient. You're better off just buying a different kiln.

Try at a electrical wholesale outlet. Don't know why you would want a auto transformer. A standard 240 to 120 transformer usually does the job and it can be run backwards or forwards. 240 primary 120 output on secondary or 120 primary 240 output on secondary. Either way you will have to know the amperage of the load to get the correct size of transformer.

Metal objects such as keys, pots, and cutlery can conduct electricity. Water (if it contains impurities), wet hands, and certain types of wood can also conduct electricity. It's important to be cautious around these items to avoid electric shocks.

There is normally no neutral point for a delta connection, Star or Y connections have grounded neutral points. So earthing transformers (or grounding transformers, GT, as they're called in this part of the world), are used to provide a neutral point in an otherwise ungrounded system. Typically they are found in utility transmission systems, where the grounding transformer provides a path for ground-fault current detection on the phases. The GT is connected in a zig-zag type arrangement such that positive-sequence (phase to phase) current is minimized, while zero-sequence (unbalanced) current presents a low-impedance path to ground. Usually, a reactor or resistor is inserted between the GT neutral connection and ground to limit the fault current to a level which will cause the detection to work but not damage the transmission equipment. See the links below for a simplified connection diagram and a somewhat more complex explanation.

I am guessing that what you are talking about is a two speed motor. The motor should have 6 wires coming out of it. There are two complete sets of three phase windings for each speed. Look on the motor name plate for the wire numbers or sometimes on the inside of the motor junction box. A 2 speed 6 lead motor should have the following markings, 1U 1V 1W for slow 2U 2V 2W for fast. Also check for the two different amp draws for each winding. These types of motors should be run from a reversing type contactor assemble so that individual overloads can be used on each of the high speed windings and on the low speed windings.

I've a 4 ft diameter ceiling fan with 3 blades of std width (about 3") hanging at a distance of 9" from the ceiling. Floor to ceiling distance is 8'5". Problem is that when I stand at a distance of about 3 to 4 feet from the centre of the fan - there is no air-flow. So, area covered by fan is 8 ft dia (max). If I stand beyond 8 ft dia circle there is hardly any air flow. Same fan in another room is hanging at a distance of about 12" to 13" and it's covering area 12 ft dia on the floor with a reasonable air-flow. It seems that there is some co-relation between height of fan from ceiling and area covered below it. Any idea? The distance from the ceiling is of little importance unless ceiling is very tall. Size of fan, width of blades makes the difference. Pitch of the blades The angle, or pitch, of each ceiling fan blade is also a determining factor in how efficient a ceiling fan will be. The angle of the blade affects the amount of wind resistance and the fan's ability to blow the circulated air downward.

As long as you don't over load the wall socket you can have a mile's worth of extension cord.

<<>>

You can not have a miles worth of cord as the voltage drop would be so high on a #14 wire that there would not be enough voltage to run the computer. Make sure that the extension cord has a ground wire in it so that the ground wire is continuous from the receptacle to the surge protector to the computer.

Electrical insulators are made from materials that are poor conductors of electricity. Metallic elements are good conductors, non metallic elements are poor conductors. Some materials used as insulators are, paper, glass, ceramics, rubber and plastics.

To find out what the wattage of your stove is look at the nameplate or check the specs. from the manual that came with it. Watts = Amps x Volts. Hypothetically your stove should be fed with a 40 amp breaker. The maximum wattage on the stove will be 40 x 240 = 9600 watts. As you can see different manufactures and different models will all be different.

Volts Alternating Current, range from a transformer and sometimes the distance of the transformer providing the volts may cause a range anywhere from 110vac to 130 volts alternating current. as long as you are within this range what ever you have should run with what voltage is provided. Yes it is all the same, it just varies.

There is no such thing as a white LED.

You produce white light from LEDs by combining red, green and blue LEDs.

Red LEDs were produced first because red is a low frequency of light. It was the easiest to make.

Green LEDs were produced next because green is a higher frequency of light. It was harder to make.

By combining red and green LEDs, you can produce yellow light.

Blue is a very high frequency of light and is very hard to produce. Blue LEDs and blue lasers (as in BluRay) took a great deal of effort to create. LED technology and some kinds of laser technology are very closely related.

Water containing dissolved ions or impurities conducts electricity well. This is because the ions in the water carry electric current. Pure water, without ions, does not conduct electricity well.

Watts = amps x volts. 1000/120 = 8.3. Assuming the oil burner motor is 120V then the generator has the ability to produce 8.3 amps. Find the amperage on the burner pump motor, if it is in this range it will work. The closer the pump amperage is to the generator output the more effect it will have on slowing the generator down on the start. Motors draw up to 300% on start up, this is what makes the generator lag when a motor is connected as a load.

There are a couple of catagories for plug descriptions. Straight blade and twist lock blade. The amperage and voltage rating is embossed on the plug (trade name for plug is cap, wall part receptacle). See related links for a chart.

The measure of how difficult it is for charges to flow through a material is called electrical resistance. It is quantified in ohms and is determined by factors such as material composition, dimensions, and temperature.

The human ear can typically detect sound waves with frequencies ranging from 20 Hz to 20,000 Hz. Sound waves with frequencies below 20 Hz are infrasound, while those above 20,000 Hz are ultrasound, which are not usually perceived by humans. The audible range of sound waves varies among individuals due to factors like age and hearing health.

The National Electric Code is updated yearly and is usually adopted by a locality some years after release. You can check with your local license and permit office what version is in effect in your locale or ask an electrician. It contains the rules for all types of electric work.

In the United States, the NEC is updated every 3 years on a very strict schedule and it is adopted by local jurisdictions at their discretion. It is not a government document until it is adopted by someone. The most recent update is the 2011 version. I know that Master Electrician tests are not yet based on it. Depending on the jurisdiction you may find a version as old as the 1999 NEC still in effect.
