Heating Effect of Current (Joule's Law)

Heating Effect of Current (Joule's Law)

### Formula

$$H=I^2Rt$$

### Alternative Forms

$$H=VIt$$

$$H=\frac{V^2t}{R}$$

### Terminologies

- H → Heat produced.

- I → Current.

- R → Resistance.

- t → Time.

### Conditions / Special Cases

Heat produced:

$$H\propto I^2$$

### Usage

- Used in heating appliances and circuit problems.
