A complete circuit contains two parallel-connected devices and a generator for providing the electromotive force. The resistance of the first device is 12 ohms, the resistance of the second device is 4 ohms, and the voltage developed by the generator is 40 V. 3.33 A is the magnitude of the current flowing through the first device. Solution: 40V = V1 =V2 Since V =IR I1 = V1/R1 I1 = (40V)/(12 ohms) I1 = 3.334 A(Amperes).
