Ifthe plus terminal of a dc voltmeter is placed between R1 and R2 (with voltages E1 and E2), and the minus terminal of the voltmeter is placed between R3 and R4(with ... resis-tance, R, of R1, R2, and R3 in parallel, and then calculating I based on R. Another, per-haps easier, way is to find the currents through R1, R2, and R3 individually, and thenadd them up.Using...
