How to transform Volts to Amps

Voltage is the potential difference in an electric circuit, measured in volts. It could be much easier to think the it together the quantity of force or press pushing electrons with a conductor. To convert volts to amps, a measure of current, it’s possible to use a formula defined by Watt’s Law.

Watt’s law states that current = strength ÷ voltage. Strength is measure up in watts and voltage is measure in volts.

Thus, to discover amps substitute the volts and also watts in the formula:Current(A) = Power(W) ÷ Voltage(V)


For example, uncover the amperage of a 100 watt light pear at 120 volts.

amps = watts ÷ voltsamps = 100 W ÷ 120 Vamps = .83 A

Convert Volts to Amps using Resistance

Ohm’s Law offers an alternate formula to find volts if amps and the electric resistance is known. To calculation amps, division the voltage by the resistance in ohms.

Current(A) = Voltage(V) ÷ Resistance(Ω)

For example, let’s find the current of a 12 volt circuit through 10 ohms of resistance.

amps = volts ÷ ohmsamps = 12 V ÷ 10 Ωamps = 1.2 A
