You are given n identical cells, each with emf E and internal resistance r = 0.2 .
Question:
You are given n identical cells, each with emf E and internal resistance r = 0.2 Ω. When these cells are connected in parallel to form a battery, and a resistance R is connected to the battery terminal, the current through R is the same as when the cells are connected in series and R is attached to the terminals of that battery. Find the value of the resistor R.
