The parallel combination of a 6.8 kΩ resistor and a 10 kΩ resistor is in series with the parallel combination of a 2.2 kΩ resistor and a 1 kΩ resistor. A 100 V source is connected across the circuit. The resistor(s) with the greatest voltage drop is (are)___________?
Correct answer: C. 6.8 kΩ and 10 kΩ
- A. 6.8 kΩ
- B. 2.2 kΩ
- C. 6.8 kΩ and 10 kΩ
- D. 2.2 kΩ and 1 kΩ
Explanation
The 6.8 kΩ and 10 kΩ parallel group has an equivalent resistance of about 4.0 kΩ, whereas the 2.2 kΩ and 1 kΩ group is about 0.69 kΩ. In series, the higher-resistance group gets the greater voltage, and both resistors in that group have the same voltage across them.
