Question

100 joule of heat are produced in each second in 4 ohm resistance find the potential difference across the resistor

Answer 1

heat produced = 100

r= 4 ohm

time = 1 sec

in one sec ...the heat energy produced =H=I*Rt

100=I*(4)(1)

I*=100/4

I=root 25=5

so I is 5

now V=IR

V=(4)(5)=20

the potential difference across the resistance is 20 V
