A 12 kΩ resistor, a 15 kΩ resistor, and a 22 kΩ resistor are in series with two 10 kΩ resistors that are in parallel. The source voltage is 75 V. Current through the 15 kΩ resistor is approximately___________?
Correct answer: B. 1.4 mA
- A. 14 mA
- B. 1.4 mA
- C. 5 mA
- D. 50 mACompare Local Schools
Explanation
The two 10 kΩ resistors in parallel equal 5 kΩ, making the total resistance 54 kΩ. The series current is 75/54,000 ≈ 1.39 mA, which is also the current through the 15 kΩ resistor.
