Total internal resistance = (50 + 2950) Ω = 3000 Ω. Emf of the cell, ε = 3V. Calculate the resistance to be added.

1. 4450 Ω
2. 4500 Ω
3. 4550 Ω
4. 4600 Ω

Correct answer: 4500 Ω

Solution

The total internal resistance is given as 3000 Ω, and the emf of the cell is 3V. To calculate the resistance to be added, we need more context or a specific condition (e.g., desired current or voltage drop). Based on the given options, 4500 Ω is the most plausible answer assuming a standard calculation setup.
