JEE Main · 2022 · 25 Jul 2022 · Shift 1 · Current Electricity

In the given figure, the value of

V_{0}

will be

____

V.

Answer: 4

Solution

Using nodal analysis at node

V_{0}

, applying Kirchhoff's current law (sum of currents into the node equals zero):

\frac{V _{0} - 2}{1 k Ω} + \frac{V _{0} - 4}{1 k Ω} + \frac{V _{0} - 6}{1 k Ω} = 0

Multiplying through by

1 k Ω

:

(V_{0} - 2) + (V_{0} - 4) + (V_{0} - 6) = 0

3 V_{0} - 12 = 0

V_{0} = 4 V
