State the condition for maximum current to be drawn from the cell.

Text Solution

AI Generated Solution

To determine the condition for maximum current to be drawn from a cell, we can analyze the circuit consisting of a battery with an electromotive force (emf) \( e \), an external resistance \( R \), and an internal resistance \( r \). ### Step-by-Step Solution: 1. **Understand the Circuit Configuration**: - We have a battery with an emf \( e \). - The battery has an internal resistance \( r \). - An external resistance \( R \) is connected across the battery. ...
