The parallel combination of a 470 Ω resistor and a 1.2 kΩ resistor is in series with the parallel combination of three 3 kΩ resistors. A 200 V source is connected across the circuit. The resistor with the most current has a value of____________?
Correct answer: C. 470 Ω
- A. 470 Ω or 1.2 kΩ
- B. 3 kΩ
- C. 470 Ω
- D. 1.2 kΩ
Explanation
The 470 Ω and 1.2 kΩ resistors share the voltage of their parallel branch, so the lower resistance carries more current. The 470 Ω resistor therefore carries the greatest current.
