Three identical cells each of 2 V and unknow internal resistance are connected in parallel. This combination is connected to a 5 ohm resistor. IF the terminal voltage across the cell is 1.5 volt, what is the internal resistance of each cell?

Explanation

To find the internal resistance of each cell when three identical cells of 2 V each are connected in parallel to a 5-ohm resistor, and the terminal voltage across the cells is 1.5 V, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Voltage of each cell (E) = 2 V
- Terminal voltage (V_t) = 1.5 V
- Resistance of the external resistor (R) = 5 Ω
