Question

A potential difference of 250 volts is applied across a resistance of 500 ohms in an electric iron.calculate the heat produce when 96000 Columbus of charge is transferred in 1 hour through a potential difference of 50 volts

Answer 1

Explanation:

9600C

1hr=3600s

i=Q/t

i=9600/3600=6A

v=50V

resistance=volt/ampere=50/6=8.33ohm

t=3600seconds

H=i^2Rt=36×8.33×3600=1079568 joules
