Q1:

In the network shown in figure, the voltage drops across R2 and R3 are 10 V and 16 V with polarities as shown. The current in R1

A is 9 A and directed towards node 0

B is 9 A and directed away from node 0

C is 9 A but directed of current cannot be found

D is impossible to be found

ANS:B - is 9 A and directed away from node 0

Current through R2 = 5 A towards 0. Current through R3 is 4 A away from node. Total incoming current = 13 A. Current going away from 0 and flowing through R1 = 9 A.
