How do you calculate amperage when given the values of watts and volts?
With an instrument called a multimeter. The single meter incorporates within it a volt meter, an ohm meter and an amp meter. For higher amperages a clamp on amp meter is recommended as the circuit does not have to be opened to take a reading.
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 much power is used by a 120 V circuit using 6 amps?
The equation that you are looking for is I = E/R. Amps = Volts/Resistance.
.01 amps equal how many volts?
Amps and volts are not the same, but related by Ohm's Law. Volts = Amps x Ohms. Ohms is a measure of resistance. Given .01 amps you would have to know resistance to calculate volts.
What is the load for a doorbell circuit?
The load on a door bell circuit is the coil of the ringer. It is dependant upon the coil resistance and the voltage the system uses. The equation to use is A = E/R, Amps = Volts/Resistance.
How do you measur ampere?
You use an "amp gauge" to measure amps in an actual circuit. It is hooked in series with the load. It can be placed anywhere in the circuit as long as it is hooked in series. Mathematically, you have to know the resistance, or wattage and voltage of a circuit. Volts=amps*resistance or amps=volts/resistance, or resistance=volts/amps. Ohms law!
What is the resistance of the circuit if the voltage is 230 volts and the current flowing is 5 amps?
The resistance of the circuit will be 46 ohms

What is the resistance of a circuit that takes a current of 0.5A when the voltage to the circuit is 40v?
The formula you are looking for is Ohms = Volts/Amps. R = E/I.
Using ohm's law what is the formula to find the resistance in a circuit?
Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)
How much power is used by a 120 V circuit using 6 amps?
The equation that you are looking for is I = E/R. Amps = Volts/Resistance.
How can you convert amperes in to volts?
Amperes does not convert into volts they are two different values. Become familiar with the following formula and look at the relationships between the values. Volts = Amps x Resistance, Amps = Volts / Resistance and Resistance = Volts / Amps.
How many amps in 120volts and 500ohms?
You use Ohm's Law to make your calculation. Volts = Amps x Resistance Amps = Volts / Resistance
.01 amps equal how many volts?
Amps and volts are not the same, but related by Ohm's Law. Volts = Amps x Ohms. Ohms is a measure of resistance. Given .01 amps you would have to know resistance to calculate volts.
Calculate the resistance in a circuit in which a 9 volt batteriyproduces 3 ampheres?
V=IR so, R=V/I or resistance = Voltage / Amps Therefore, the resistance (R) = 9 volts / 3 Amps answer: 3 Ohms
Do resistors lower volts or amps?
Current is directly proportional to the applied emf (voltage) and inversely proportional to the resistance of the circuit.
