Question

State Joule's law of heating. Write its mathematical form both in C.G.S system and SI.​

Answer 1

Answer:

According to the Joule's law, when a current is passed through a conductor for a certain time, the conductor gets heated up and the amount of heat is given by :

$\pink{H =i²Rt}$

H is the heat, i is the current, R is the resistance and t is the time.

(i) square of current for a given resistance

(ii) resistance for a given current. and

(iii) the time for which the current flows through the resistor.

Mathematical form : H = I²Rt
