### Watts to Amps Conversion:

This watts to amps calculator is also known as amps to watts calculator or amperage calculator. It helps to understand how to calculate the watts of a circuit depending on the type of current.

Learn about converting watts to amps and vice versa and the differences between line-to-line and line-to-neutral voltage configurations used for three-phase currents. See more sections to know how to convert watts to amps, their formulas and solved example questions.

- Get power and voltage.
- Divide the voltage by the volts in watts to get the DC amps.
- Get the power factor method volts.
- To get amps in AC, divide the power by the product.

### Watts to Amps Formula:

Watts to amps formula current I_{(A)} in Ampere is equal to the power P_{(w)} in watts and multiply the voltage V_{(v)} in volts.Hence the watts to amps formula can be written as

I_{(A)}= P_{(w)} *V_{(v)}

#### Ac single phase watts to amps

I= P / (PF *V)

#### Ac three phase watts to amps

I= P/ (√ 3* PF *V)

I= is the current in amps

P= is the power in watts

PF= is the power factor

V= is the voltage in volts

### Example:1

Convert 45 watts having 18v and 4 power factor to single phase Ac amps

### Answer:

Given that

Power P =45 w

Voltage v = 18V

Power factor PF = 4

Current I = P / (PF *V)

I= 45 / (4 * 18 )

I=45/72

I=0.625A

Therefore, single phase Ac amps is 0.625 A

### Example:2

Convert 23 watts having 20 v power factor to single phase Dc amps?

### Answer:

Power =23w

Voltage =20v

By using formula

I= P *V

I=23/20

I=1.15 Ampere
