Step 1: Analyze the circuit and given information. The circuit consists of three 1.5 V cells connected in series, providing a total electromotive force (EMF) of: EMF_total = 3 × 1.5 V = 4.5 V There is a parallel combination of two resistors: • A resistor R_1 = 2 (under V1). • An unknown resistor R_2 (under V2). The combined parallel resistance is given as R_parallel = 1.5 . This parallel combination is in series with another resistor R_3 = 1 (under V4).
