Question

calculate the amount of heat generated when 18000 coulombs of charge is transferred in one hour through a potential difference of 50v

Answer 1

Answer:

C=18000

V=50v

T=1hour

firstly we have to find the current

so (I=Q/T)

I=18000/60*60

I=5A

Now,we have to calculate the resistance-

V=IR

so,R= V/I

R=50/5

R=10ohm

Now, Heat=I^2*R*T

H=5^2*10*60*60

H=25*36000

H= 900000Joule
