A closed loop consists of a 15 V battery, a 5 V battery (opposing the first), and a 25 resistor. The current through the loop is
Options
- A0.8 A
- B0.2 A
- C1.2 A
- D0.4 A
Correct answer
D. 0.4 A
Step-by-step solution
The net electromotive force in the loop is the difference between the two opposing batteries. E_ net = 15 - 5 = 10 V The total resistance in the loop is R = 25 . Using Ohm's law, the current I is given by: I = E_ net R = 10 25 = 0.4 A Answer: 0.4 A
