Derivation for Joules heating effect
Answers
Answer:
hi mate,
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. The power P has units of watts, or joules per second, when the current is expressed in amperes and the resistance in ohms.

Answer:
The heat that is generated because of the current flow in an electric wire is described in Joules. The mathematical expression of Joule’s law is as explained below.
Joule’s first law
The joule’s first law shows the relationship between heat produced by a flowing electric current through a conductor.
Q = I2 R T
Where,
Q indicates the amount of heat
I show electric current
R is the amount of electric resistance in the conductor
T denotes time
