To find the internal resistance of a cell that develops the same power across two resistances \( R_1 \) and \( R_2 \), we can follow these steps: ### Step 1: Understand the Power Formula The power \( P \) across a resistor \( R \) connected to a cell with electromotive force \( \epsilon \) and internal resistance \( r \) can be expressed as: \[ P = I^2 R \] where \( I \) is the current flowing through the resistor. ...
