The current I drawn from the 5 volt source will be
(A)0.17 A
(B)0.33 A
(C)0.5 A✓ Correct
(D)0.67 A
Answer: (C)
Solution
The resistors in the figure form a bridge-type network fed by the 5 V source. Working through the series and parallel combinations shown, the network reduces to a single equivalent resistance of 10Ω between the terminals of the source. The current drawn then follows from Ohm's law, I=ReqV=105=0.5 A.
