Question

state jouels law of heating and derive the formula​

Answer 1

Explanation:

the higher the current the larger the amount of heat generated. Hence the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t is given by H = I2Rt. This equation is called the Joule's equation of electrical heating.

Answer 2

Answer:

Joule’s law of heating states that,

Joule’s law of heating states that,when a current ‘i ' passes through a conductor of resistance ‘r’ for time ‘t’ then the heat developed in the conductor is equal to the product of the square of the current, the resistance and time.

It's Formula:

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 :

H=i²Rt

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