Question

A resistor of resistance 12 Ω has a current of 2.0 a flowing through it. How much energy is generated in the resistor in 1 minute?

Answer 1

Solution;

Given;

Resistance,R=$12\Omega$

Current,I=$2A$

Time,t=$1m=60s$

Hence;

Power in the resistor is;

$P=I^2R$

$P=2^2×12=48W$

Energy generated is;

$E=Pt$

$E=48×60=2880J$
