Question

For the circuit shown below, voltage  Vwill be 


A.

2.64 

B.

3.64 V

C.

6.0 V

D.

9.1 V

Answer ( Option C)

6.0 V

Solution

The direction of the current flow is shown in figure below :

Applying KCL (Kirchhoff’s Current Law) at node x, we have,

Similarly, applying KCL at nodey,

On solving equation (i) and (ii), we get

Hence, the correct option is (C).

&Key Points:-

Kirchhoff’s current law states that for a parallel path, the total current entering the circuit’s junction is exactly equal to the total current leaving the same junction.
