.01 amps equal how many volts?
To calculate volts, you also need to know the resistance (ohms) in the circuit according to Ohm's Law. The formula to find volts is V = I x R, where V is voltage, I is current in amps, and R is resistance in ohms. So, to determine volts given 0.01 amps, you'd need the resistance value.
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?
The resistance of a 5.0 kW heat strip can be calculated using Ohm's Law (Resistance = Voltage^2 / Power). Assuming the heat strip operates at 240 volts, the resistance would be approximately 115.2 ohms.
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 many volts is 7.5 amps?
To find the voltage, you would need to know the resistance. Using Ohm's Law (voltage = current x resistance), you can find the voltage. If the resistance is not given, you cannot directly convert amps to volts.
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 power used by the circuit can be calculated using the formula P = V x I, where P is power in watts, V is voltage in volts, and I is current in amps. In this case, P = 120 V x 6 A = 720 watts. Therefore, the circuit is using 720 watts of power.
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 much resistance should be on a 5.0 kw heat strip?
The resistance of a 5.0 kW heat strip can be calculated using Ohm's Law (Resistance = Voltage^2 / Power). Assuming the heat strip operates at 240 volts, the resistance would be approximately 115.2 ohms.
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?
To calculate volts, you also need to know the resistance (ohms) in the circuit according to Ohm's Law. The formula to find volts is V = I x R, where V is voltage, I is current in amps, and R is resistance in ohms. So, to determine volts given 0.01 amps, you'd need the resistance value.
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.
