Two cells of emfs 1.5 V and 2.0v having internal resistance 0.2`Sigma` and 0.3 `Sigma` respectively are connected in parallel . Calculate the emf and internal resistance of the equivalent cell .

Explanation

To solve the problem of finding the equivalent emf and internal resistance of two cells connected in parallel, we can follow these steps:

### Step 1: Identify the given values
- For Cell 1:
- Emf (E1) = 1.5 V
- Internal resistance (r1) = 0.2 Ω
- For Cell 2:
- Emf (E2) = 2.0 V
