The amount of generated heat is proportional to wire's electrical resistance when the current in the circuit and the flow of current is not changed.

Mathematically , Q= I2 R T

Where , Q refers to amount of heat,

I means electric current,

R is the amount of electric resistance in conductor and

T is time.

Answer:

Joule's law states the amount of heatproduction in a conductor is : Directly proportional to the square of electric current flowing through it. Is directly proportional to the resistance of the conductor. Directly proportional to the time for which electric current flows through the conductor.

formula is Q = I^2 R T

Explanation:

Joyless law of hearing is about on hearing.

It is expressed as

H= I²Rt (or) V²/R×t

where (I=V/R).

In this, H= heat of the substance

I= current through the substance

R= resistance

T= temperature.

hope this helps you a little!!!
