Question

According to the joules law, heat is directly proportional to the square of current, resistance and time. So, It should be H∝I^2×R×t. So for solving this further, a constant has to be added. But In the books it's directly written as H=I^2×R×t. Where did the constant go?

​

Answer 1

Answer:

First of all,constant is the part that doesn't change during the experiment

Explanation:

we take constant bcz It will be assumed as just a no. to solve or find formula we will assume constant

For example: In ohms law,

v is directly proportional to current I

V=RI where R is the proportionality constant and is called as resistance
