Question

The current I drawn from the 5volt source will be

(a) 0.17 A 

(b) 0.33 A

(c) 0.5 A 

(d) 0.67 A.

Answer 1

(c) : The equivalent circuit is a balanced Wheatstone's bridge. Hence no current flows through arm BD.

AB and BC are in series
Therefore, R_ABC = 5 + 10 = 15W AD and DC are in series
