To solve the problem of arranging 100 cells, each with an EMF of 5V and an internal resistance of 1Ω, to produce maximum current in a 25Ω resistance, we will follow these steps: ### Step 1: Understand the Configuration We have 100 cells, each with: - EMF (E) = 5V - Internal resistance (r) = 1Ω We need to arrange these cells in rows, with each row having an equal number of cells. The goal is to maximize the current through a 25Ω external resistance (R). ...
