39. 'p' identical cells, each of emf E and internal resistance r, are ...
- **Given:**
- Number of identical cells, 'p'
- Each cell has an EMF E and internal resistance r
- Cells are connected in parallel
- External resistance R is connected across the parallel combination of cells
- **To find:**
- Current through the external resistance, I
- **Formula:**
- Total EMF of 'p' cells in parallel, E_total = E
- Total internal resistance of 'p' cells in parallel, r_total = r/p
- Total current, I = E_total / (R + r_total)
- **Explanation:**
- When 'p' identical cells are connected in parallel, the total EMF remains the same as that of a single cell, E_total = E
- The total internal resistance of 'p' cells in parallel is given by r_total = r/p
- The total current flowing through the circuit is given by Ohm's Law, I = E_total / (R + r_total)
- Substituting the values of E_total and r_total, we get I = E / (R + r/p)
- **Conclusion:**
- The current through the external resistance R in a circuit with 'p' identical cells connected in parallel can be calculated using the formula I = E / (R + r/p)
