Question

Calculate the amount of heat generated when 7200 coulombs of charge is transferred in one hour through a 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

Answer 2

Answer:

the answer is 100j

Explanation:

v2×t/R
