TripletheCurrent 001 10.0points The current in a circuit is tripled by connect- ing a 774 Ω resistor parallel with the resis- tance of the circuit. Determine the resistance of the circuit in the absence of the 774 Ω resistor. Correct answer: 1548 Ω. ResistanceCircuit04 002 10.0points Consider the circuit 7 . 5 Ω 15 Ω 15 Ω 7 . 5 Ω 15 Ω a b What is the equivalent resistance between the points a and b ? Correct answer: 13 . 125 Ω. SerwayCP1820 003(part1of2)10.0points In the circuit of the figure, the current I 1 is 3 . 6 A and the value of E 2 is unknown. a b 28 V E 2 3 . 6 A 7 . 5 Ω I 2 2 Ω I 3 6 . 9 Ω What is the magnitude of the current I 2 ? Correct answer: 0 . 5 A. 004(part2of2)10.0points Find I 3 . Correct answer: 3 . 1 A. InternalResistance02 005(part1of2)10.0points A battery with an emf of 7 . 9 V and internal resistance of 1 . 37 Ω is connected across a load resistor R . If the current in the circuit is 0 . 88 A, what is the value of R ? Correct answer: 7 . 60727 Ω. 006(part2of2)10.0points
