joules law of heating(plzzzzz answer quickly)

Expert Answer:

Joule's law of heating states that the rate of heat dissipation in a resistive conductor is proportional to the square of the current through it and to its resistance. That is, the power dissipated in a resistor, in terms of the current through it and its resistance, is:

H = I2Rt

For example, electric heater, electric iron.
