On a 220 volt circuit where the white wire is common how many volts would the red wire be?
Robertjudeq
3 OR 4 . you only need 2 wires for 220, 1 phase is 120v between 2 of them its 220v . you also should have a ground for the third wire ,and the newer stuff requires a neutral or white wire for the 4th wire. hope i helped , D

How do you rewire a 220 volt receptacle to produce 110 volts?
A 220 volt receptacle is a receptacle which has 2 wires carrying 110 volts...it has two "hot" wires at 110 and a neutral or common leg which has no voltage. A 110 volt receptacle is a receptacle which has 1 wire which carries 110 volts and a common wire. The wiring in the USA is almost standardized now to where the two "hot" (carrying 110 volts) wires are colored black and red, and the common or neutral is white. To change a receptacle to 110 volts..you remove the red or black wire from the old receptacle and wire nut it off...leaving the other red or black to attach to the new receptacle (right side of receptacle usually, looking at it from the grounding hole on the receptacle ON THE BOTTOM). You then connect the white wire to the left side of the receptacle. This will provide only 110 volts now. If the wires are not black, red, and white..they may be black, black, and white. In most cases, the white wire is always the neutral or common wire. When in doubt, buy a voltmeter and check each wire to the metal box in the wall...the wires carrying the 110 volts will usually read 110 on the voltmeter (or 115, 118..etc). Good luck!
How much resistance should be on a 5.0 kw heat strip?
Depends on the voltage. Wattage is Volts x Amps. Resistance (ohms) is Volts divided by Amps. So on a 120V circuit, it would draw 41.66 amps. To do that, it would need a resistance of 2.88 ohms. But on a 240V circuit, it would draw 20.83 amps. That would require a resistance of 11.52 ohms. Determine the circuit voltage, then use that to figure the amps, then use that result to calculate the resistance necessary.
How do you change 110 volts to 240 volts?
You need to change the circuit breaker and sometimes the wiring itself. For example, if you have a 120 volt circuit with a black wire as the hot and the white as a neutral you would take the white wire off the neutral bar of the circuit breaker panel and put it on one leg of a 240 volt breaker. The receptacle would have to be changed as well. The white wire should be re colored to black or red.
How many watts per outlet?
No way of telling unless you know the current of all devices that use the circuit. The maximum wattage for the circuit, assuming a resistive load (no motors) would be: Watts = Volts x Current.
How many volts is 2 gauge 200 amp 3 ohms?
Ohm's Law states Volts = Amps x Resistance. You would need to apply 600 volts across 3 ohm load to have 200 Amps flow in circuit. Not sure what you are really asking and why you mentioned 2 gauge.
A circuit has an applied voltage of 100 volts and a resistance of 1000 ohms What is the current flow in the circuit?
A circuit has an applied voltage of 100 volts and a resistance of 1000 ohms. The current flow in the circuit is 100v/1000ohms which would equal .1.
What is the curren in an ac circuit with 120 volts and a 60 watt light bulb?
You want to know how many amps in that circuit. To do so, divide the Watts by the Volts. in your case it would be 60 watts / 120 volts = 0.5 Amps.
What would be the voltage suplied to each circuit if three circuits are connected in parallel with a power supply of 30 volts?
30 volts.
If 3 1.5 V cells were connected in series what would the total voltage of the circuit be What about in Parallel?
4.5 volts in series; 1.5 volts in parallel.
What a circuit of hair dryer 1200 watts 240 v?
Watts equals volts multiplied by amps. This would therefore be a five amp circuit.
How much Ampere when volt 415?
That would depend on the power output (watts) of the circuit. Volts times the Amperage equals the Wattage of the circuit. You do not have enough information in your question. Volts is the force applied to move the electrons in the circuit, and amps are a measure of the quantity of electrons moved through the circuit over time. Thus a circuit of 415 volts and 1 ampere will deliver 415 watt-hours of power. Yet a circuit of 1 volt at 415 amps will deliver the same 415 watt-hours of power, but with less force.
What fuse would you use in a circuit with a 1kw load and a 250 volts supply show calculation?

120 volts equal how many watts?
It depends upon how much amperage is utilized in a circuit. A circuit with 2 amps of current and 120 volts would consume 240 watts of power. The same circuit with 4 amps would produce 480 watts. You have to have 2 values of Ohm's law to figure out the third. See "Ohm's law" on the internet for more information on how circuit values are determined.
What kind of circuit is most common in your homes?
The most common circuit is the parallel circuit. If you notice, on a chandelier, if one goes out the rest stay on. If you would have a series circuit then your house lights would be very dim because of all the usage of lights.
How do you convert 12 volts to 3 volts with resistors?
Calculate the impedence of your 3V circuit in ohms. Figure the voltage you want to drop. In this case, you need to lose 9V. This is three times the voltage you are supplying, so the resistor should have three times the resistence of your 3V circuit. If your circuit has 100 ohms of resistence (impedence), then you would connect a 300 ohm resistor in series with your circuit.
What would the voltage be if you had 78 volts with a parallel circuit of 10k 10k 10k 10k 5k?
because the circuit you have quoted is a parrallel type, the voltage will be the same across all the components/ resistors in parallel . -- 78 volts. however i wonder if you needed to calcualte the current flow
