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

12.5 Ω
200 Ω
20 KΩ
50 Ω

Correct Answer: 20 KΩ

Explanation:

10/(R/4) = 2 mA
40/R = 2 mA
R = 40/2 mA
= 40/0.002 A
= 20000 kohm (20 kohm)
