Three 10 kΩ resistors are connected in series. A 20 kΩ resistor is connected in parallel across one of the 10 kΩ resistors. The voltage source is 24 V. The total current in the circuit is___________?
Correct answer: A. 900 μA
- A. 900 μA
- B. 9 mA
- C. 90 mA
- D. 800 μA
Explanation
The shunted section has an equivalent resistance of 10 kΩ || 20 kΩ = 6.67 kΩ, giving a total resistance of 26.67 kΩ. Thus the source current is 24/26.67 kΩ, approximately 900 μA.
