  1. In figure, the value of the source voltage is—


    1. 12V
    2. 24V
    3. 50V
    4. 44V
Correct Option: C

The given figure

Applying KCL at node C, we get

=
VC - 0
 = 1 + 2
10

or
VC = 30V
and
=
Vs - VC
 = 2
10

or
VS = 20 + Vc = 20 + 30
= 50V
Hence alternative (C) is the correct choice.
