Enter the electric power in W (Watts):
Enter the voltage in V (Volts):
(the most common voltage standard is 230 and 120 volts)
Current in A (Amps) is:
0.00A
How to calculate the current in amperes if the power and voltage are known?
Amperes are determined by dividing Watts by Volts.
I = P / U, where
I is the current in amperes (A);
P is the power in Watts (W);
U is the voltage in volts (V).
For example:
Convert 3500 Watts to Amps if the voltage is 120 V:
I = P/V=3500 / 120 =29,16 A
Convert 3500 Watts to Amps if the voltage is 230 V:
I = P/V=3500 / 230 =15,22 A
Convert 1800 Watts to Amps if the voltage is 120 V:
I = P/V=1800 / 120 =15 A
Convert 1800 Watts to Amps if the voltage is 230 V:
I = P/V=1800 / 230 =7,83 A
Convert 150 Watts to Amps if the voltage is 120 V:
I = P/V=150 / 120 = 1,25 A
Convert 150 Watts to Amps if the voltage is 230 V:
I = P/V=150 / 230 =0,65 A
