Question

formula for the joule law of heating

Answer 1

The most general and fundamental formula for Joule heating is: P is the power (energy per unit time) converted from electrical energy to thermal energy, I is the current travelling through the resistor or other element, is the voltage drop across the element.

Answer 2

Heat =

${i}^{2} \times r \times t$

Where I is the current

R is the resistance

T is time
