Question

The potential difference between the terminal of an electric heater is 60V when it draws current 4a from the source what current will thy heater if the potential difference increased to120v

Answer 1

v=60; I =4ampere according to ohms law R=V/I =60/4=15 ohms I=120 /15=8A

Answer 2

ans. V=60V
I=4AMP.
R=V/I=60/4=15 ohm
second case.....
V=120V
R=15 ohm
I=V/R=120/15=8amp.
I=8ampere
