Reference Code: 21M.1A.SL.TZ2.17
A circuit contains a variable resistor of maximum resistance R and a fixed resistor, also of resistance R, connected in series. The emf of the battery is
6.0 V and its internal resistance is negligible. What are the initial and final voltmeter readings when the variable resistor is increased from an initial resistance of zero to a final resistance of R?
