How many watts is 8 amps at 240 volts?

Answer 1

P = E^2 / R

P = (240 x 240)/ 8 = 7200 watts

If this is coninuously energized for 24 hours:

7.2 kw/hr x 24 = 172.8 kw/hrs

Answer 2

8 amps at 240 volts is equal to 1920 watts. This calculation is done by multiplying the current (8 amps) by the voltage (240 volts) to get the power in watts.

Answer 3

The power consumed by the element is P=(v)*(v)/R

P=(240)*(240)/8=7200w.

Answer 4

1920 watts, or, at the risk of confusing you, 1920 volt-amps for non-resistive loads such as motors.
