Electric Current

Electric Current

Electric current is the rate of flow of electric charge through a conductor.

### Formula

$$I=\frac{Q}{t}$$

### Terminologies

- I → Electric current.

- Q → Charge flowing through conductor.

- t → Time.

### SI Unit

$$Ampere(A)$$

### Dimensions

$$[I]=[A]$$

### Conditions / Special Cases

- Conventional current flows from positive to negative terminal.

- Electron flow is opposite to conventional current.

### Usage

- Used to calculate charge flow in circuits.
