Question

2A current flows through an electrical device of resistance 120.
a) calculate power of the device.
​

Answer 1

Answer:

Given ,

Resistance = 120 ohm

Current = 2A

ACCORDING TO OHM'S LAW ,

V = IR => V = (120×2) VOLT = 240 V

NOW, WE KNOW THAT,

P = VI => P = (240×2) WATT = 480 WATT

HENCE THE REQUIRED ANSWER :

$480 \: \: watt$
