Question

state joules law of heating. write expression of it​

Answer 1

He determined that the heat evolved per second is equivalent to the electric power absorbed, or the power loss. A quantitative form of Joule's law is that the heat evolved per second, or the electric power loss, P, equals the current I squared times the resistance R, or P = I2R.

Answer 2

Answer:

The heat evolved per second is equivalent to the electric power absorbed, or the power loss is called joules law.

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

H is the heat,

I is the current,

R is the resistance and

t is the time.
