Question

50j of heat is produced each second in a 2ohm resistor.Find the potential difference across the resistor.

Answer 1

energy = power × time
E = P×t
E = V^2/R×t
V^2= E×R/t
=50×2/1
=100
V = root 100
= 10 volt.....ans..

Answer 2

The potential difference is actually the electrical pressure difference between two seperate terminals,in an electronic circuit.

To calculate any potential difference,we have to do the following calculations:

E(Energy) = P(Power)×t(Time)

E = V²÷R×t

V²= E×R×t

V²=50×2÷1

V²=100

V = √ 100

V = 10

So,the potential difference of the given electronic circuit is 10 volt.(ans.)
