Question

Find the equivalent resistance across two ends A and B of the circuit. Calculate the amount of heat generated when 7200 coloumb of charge is transfered in 1 hour to the potential difference of 50 V​

Answer 1

Given:-

Q=7200C

t= 1 h ->3600s

 I=Q/t

 I=7200/3600

  =2A

R=V/I

R=50/2

R=25Ω

E=VxV/Rxt

E=50x50/25x1

E=2500/25

E=100J
