Cells in Parallel Combination

Cells in Parallel Combination

### Equivalent EMF

$$E_{eq}=E$$

### Equivalent Internal Resistance

$$r_{eq}=\frac{r}{n}$$

### Terminologies

- Eeq → Equivalent EMF.

- r → Internal resistance of one cell.

- n → Number of identical cells.

### Conditions / Special Cases

- Parallel combination reduces internal resistance.

- Used when higher current capacity is required.

### Usage

- Used in battery combinations.
