The current I1 (in A) flowing through 1Ω resistor in the following circuit is
(A)0.25
(B)0.4
(C)0.2✓ Correct
(D)0.5
Answer: (C)
Solution
The source drives a total current I=RtotalV=2.51=0.4A. The two equal 1Ω resistors sit in parallel, so this current divides equally between them, and the current through the chosen 1Ω resistor is I1=20.4=0.2A.
