Watts(W) = Amps(A) × Volts(V)

From the above equation, to find the current (Amps) when the power (Watts) is known, the formula is:

Amps(A) = Watts(W) / Volts(V)

​This formula assumes a purely resistive load (meaning no phase difference between current and voltage), which is often a good approximation for many devices but not all. For devices with a reactive load (like motors or transformers), power factor correction would be required.

### Solved Example

Q. You have a 100-watt light bulb operating at 120 volts.

Ans. To find out how many amps this light bulb uses:

Amps= 100 watts/120 volts

Amps=0.8333

So, the bulb uses 0.8333 amps at 120 volts.

## FAQs on How to convert 1 watt to amps

### How many amps is 1 watt?

The amps for 1 watt depend on the voltage. Using the formula Watts=Volts × Amps, if you know the voltage, you can find the amps.

### How do you convert watt to amp?

To convert watts to amps, use the formula: Amps = Watts ÷ Volts. You need to know the voltage to determine the amps.

### How much current is 1 watt?

The current for 1 watt varies based on voltage. Use the formula: Amps = Watts ÷ Volts to determine the current.

### What is 1 ampere equal to?

1 ampere (amp) is equal to a flow of 1 coulomb of electric charge per second.

### How much is 1 amp of current?

1 amp of current represents a flow of 1 coulomb of electric charge passing a point in 1 second.
