20j of heat is produced in Isec from the
resistor of resistance 8ohm. find the
potential difference across the resistor
&
find
it's power​

Answer 1

Answer:

Heat produced = 100 J  

Time = 1 second

Resistance across the resistor = 4 ohm

To find:

Potential resistance across the resistor

Solution:

We know that heating effect of electric current,

The above relation of the heating effect can also be written as,

Here, I=5, and R=4 ohm

Therefore, the resistor's potential difference is 20 V
