how to convert Watts to Amps

how to calculate Watts to Amps

1. DC Voltage

I = P / V

Example:

P = 60
V = 12
I = 60W / 12V

I = 5A

2. Single phase voltage

I = P / (PF × V )

Example:
P = 920
P.F = 0.8
V = 230

I = 920W / ( 0.8 PF × 230V )

I = 5A

3. Three phase voltage

I = P / ( √3   × PF  × V )

Example:

I = 2875.12 / ( √3 × 0.8PF ×415 V )

I = 2875.12 / 575.024

I = 5A
