What would happen if you use one leg of a 220 circuit and it's neutral to power a 110 light?

it will lite . <P>
<P></P>Well, you sorta answered your own question, if you are talking residential wiring. The transformer in front of the house supplies 220V, center tapped, to your house. (we are talking the USA, right?) Center tapped means that the secondary of the transformer feeding your house is supplying 220, but there is a wire in the center of the secondary coil that has 110 between it and either end of the coil. If you look in your fusebox (breaker box in any newer home) you will see breakers on the left and on the right. The ones on the left side supply power from one end of the coil into your house and the center tap, and the ones on the other side supply power from the other end of the secondary and the center tap. 220 volts goes from either end of the secondary and doesn't bother with the center tap. I think the answer to the question is, you'll make light. be careful fooling with the cords, though.

Which is the lowest potential point in circuit for nodal analysis?
The negative (or neutral) terminal of the power source.
What happens when a circuit is not complete?
a complete circuit is a circuit through which a current can flow(see closed circuit)A complete circuit is almost like a circle. Energy flows through this circle in order to make the light bulb light.A circuit that has a power source, a load such as a light or motor to power and a ground point.A complete circut is a circut with no gaps.
Why an electrical device will not work if the neutral is not connected in a single phase system?
To make any electrical circuit work it has to be complete. Source of power to the load, the load itself and a return path from the load back to the source. The source in this case being the distribution panel. Any breaks in this complete path will cause the current to stop flowing and the device to not work. A light fixture and light switch work on this principle, open the circuit and the light goes out.
What does Ohm's law imply will happen when electrons are pushed through a circuit with great force?
more power
What is One everyday use of a series circuit?
The average light fixture is likely in series with the light switch, and the utility power grid.
What is a neutral used for in a socket circuit?
The Neutral is used to bring power back to the source to complete circuit
What is the function of neutral wires?
to complete the circuit and back to power supply
Why does not tester light up when it is touched to neutral of 3 pin socket?
Because the neutral is simply the return path in a complete circuit. It doesn't carry any power - that's only found in the live wire.
In which circuit will the light bulb be the brightest?
the circuit which has the maximum power output
Can you replace wall light switch with a PIR switch if Wall switch has usual live neutral and earth but PIR has live in live out and neutral.?
An ordinary light switch does NOT have any neutral -- it only switches the live wire. Some installers use the white wire as a "switched" wire to the light fixture, where the power cable went to the light and a separate cable went to the switch. Technically, the white wire should have been marked with red or black tape at each end, to signify it is not neutral - it is either live or off. In that case, you would not be able to use a PIR switch because there is no neutral, which is necessary to provide power to the electronic circuit in the PIR. You would need to rewire the switch with a new power cable from the branch circuit. The you have the live and neutral wires in the outlet box, connect them to the PIR, and run the pigtailed neutral and the switched live (and pigtailed ground) to the light fixture (where you would disconnect the other power cable completely and cap the ends separately).
What job does a bulb do in a circuit?
The bulb converts energy from the power source into light and heat. It is the load in the circuit.
How does a 3000gt neutral safety switch work?
a neutral safety switch only allows the car to start when the gearshift is in park or neutral. It is normally located on the top of the transmission. the switch closes the circuit so power can be sent to the starter circuit.
What happen in a parellel circuit when the light bulb burn out?
The other bulbs continue to glow, with the same power as before. The total current and power decreases by the amount lost to the one bulb.
What will happen to the circuit if the bulb if removed from its holder?
Nothing will happen to circuit..... as usual the circuit would be supplying 220v(if india) and certain current...but there is no bulb to consume power...
Which is the lowest potential point in circuit for nodal analysis?
The negative (or neutral) terminal of the power source.
How does neutral missing protection work in single phase energy meter?
need to add one power current transformer and small rectifier circuit, which will give power to the meters when the neutral is missing.
What does the wire do in an electric circuit?
The neutral wire is a return wire for the current in an electrical circuit. Do not confuse for the ground wire which is also a return wire but is used in the event the connected appliance shorts to protect the user from electrical shock. The neutral is actually very similar to the ground, though. In a residence the neutral comes from the power plant, whereas the ground comes from a ground rod below the meter. In most older homes the ground and neutral were connected to the same bar in the breaker box. In newer homes they now have separate bars. Here is something interesting about the neutral wire. If you are testing a live circuit using a static checker, the neutral will not show a charge, only the hot wire will. However, if you had a circuit controlling some device (maybe a light fixture) and the light fixture was in the on position, but the neutral was cut you would notice the two wires slightly sparking when you touch them together. If you were to complete this circuit with your body you will get shocked or electrocuted. If the device were in the off position you would be safe, but don't take any chances when working with electricity. Turn off the power first.
