Expert Solution

Step 1

Nodal Analysis - It is used to find node voltage using Kirchhoff's current law.

Kirchhoff's current law- The algebraic sum of current at any node of the circuit is zero.

$I_{1} + I_{2} + I_{3} - I_{4} - I_{5} = 0$

Kirchhoff's current law also indicates the law of conservation of charges and also be stated as at any node of the circuit at every instant of time of the sum of the incoming current in the sum of outgoing current.
