Answer:

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:

H= I^2Rt

Explanation:

1- Heat is directly proportional to (I)^2. (I= Current)

2- Heat is directly proportional to (R).

(R=Resistance)

3-Heat is directly proportional to (t)

(t= time in seconds)
