Parallel Circuits – 19

5555555555

19. 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 ________.

(a) 12.5 Ω
(b) 200 Ω
(c) 20 KΩ
(d) 50Ω

Answer
Answer : (c)
Explanation
Explanation : 10/(R/4) = 2 mA 40/R = 2 mA R = 40/2 mA = 40/0.002 A = 20000 kohm (20 kohm)
