Current in Non-Uniform Conductor

Current in Non-Uniform Conductor

### Formula

$$I=J A$$

### Current Density

$$J=\sigma E$$

### Terminologies

- J → Current density.

- σ → Conductivity.

- E → Electric field.

### Conditions / Special Cases

Current remains same in steady state:

$$I=constant$$

### Usage

- Used in variable cross-section conductor problems.
