Four equal-value resistors are connected in parallel. Ten volts are applied across the parallel circuit and 2 mA are measured from the source. The value of each resistor is______________?
Correct answer: C. 20 KΩ
- A. 12.5 Ω
- B. 200 Ω
- C. 20 KΩ
- D. 50 Ω
Explanation
The total equivalent resistance is V/I = 10 V/2 mA = 5 kΩ. With four equal resistors in parallel, each resistor is four times the equivalent value, so R = 20 kΩ.
