Conversion of Galvanometer into Ammeter

Conversion of Galvanometer into Ammeter

### Formula

$$S=\frac{I_gG}{I-I_g}$$

### Terminologies

- S → Shunt resistance.

- Ig → Galvanometer current.

- G → Galvanometer resistance.

- I → Desired current range.

### Conditions / Special Cases

Shunt is connected parallel to galvanometer.

### Usage

- Used to increase current range.
