Question

joules law and formulas​

Answer 1

Answer:

Explanation:

There are two laws that are attributed to James Prescott Joule. The first law is about the heat produced by electric current and the second law is about the dependence of energy of a gas on its temperature.

Joule’s first law states that the heat H produced by current in a conductor is directly proportional to the square of the current I, the resistance of the conductor R, and the time for which the current exists t. In mathematical terms:

H∝I²Rt

Joule’s second law states that the internal energy/total energy of a gas depends on its temperature and not on its pressure and volume.

Answer 2

$\large\tt\pink{Joule's\:Law\:of\: Heating\: Effect\:of\: current→}$

It states that heat produce in a resistor is:-

1. directly proportional to square of current, $\large\tt\pink{H∝I²}$
2. directly proportional to resistance for a given current, $\large\tt\pink{H∝R}$
3. directly proportional to time for which current flows through the conductor, $\large\tt\pink{H∝t}$

So, $\:\:\:\:\:\:\:\:\:\huge\tt\pink{H∝I²Rt}$
