Question

If you know the power rating of an appliance and the voltage of the line it is attracted to , you can calculate the current the appliance uses by

Answer 1

                                Power = (voltage) times (current)

Divide each side
by voltage:              Power / voltage  =  current .

If you know the power and the voltage, then you can divide
the power by the voltage, and the quotient is the current.

Answer 2

Dividing The Power by the voltage im pretty sure.
