an electric motor draws a current of 11.5a in a 240v circuit. what is the power of this motor in watts?
Wikipedia says... P = IV where P is the power (watt or W) I is the current (ampere or A) V is the potential difference (volt or V) Watts usually expressed in Volt Amperes (v X a) 276 Watts
P=VI P=240*11.5 P=2760Watts
No. I think it's 2760 Watts. P=IV P is the power (watt or W) I is the current (ampere or A) V is the potential difference (volt or V) P =(11.5 A)(240V) P = 2760 W
P = 11.5 x 240 watts skipping things like VA and Power Factor. .
If its an ac motor, you do not have enough information. You would need to know the power factor or use a power meter to measure the power directly. Also, are you looking for the power taken by the motor or the power given out? They are different. Usually the power will be stamped on the nameplate, this will be output power. Power does NOT equal volts times amps in ac circuits despite how many people try to say it does. It's not half either
