# Convert from Watts to Amps

1) What is the current in amps when the power consumption is 100 watts and the voltage supply is 12 volts?

A = W / V

*I* = 100W / 12V = 8.33A or

8.33A * 12V= 100W

2) What is the current in amps when the power consumption is 100 watts, the power factor is 80%, and the voltage supply is 12 volts?

A = W / (*PF*× V)

*I*= 100W / (0.8 ×12V) = 10.41A or

10.41A * 12V= 125W
