Nodal Analysis

In the analysis of any electric circuit, nodal analysis is the method of determining the potential difference or voltage between different nodes in an electric circuit. A node is a point where two or more branches connect each other. In the nodal analysis, the voltages are determined in the terms of branch currents. The nodal analysis is also known as the node voltage method or branch current method. The nodal analysis method is one of the several applications of Kirchhoff's Current Law (KCL).

Expert Solution

Step 1

Referring to the above circuit, the resistance 8-Ohm and 4-Ohm are connected in series which is equivalent to 12-ohm.

And that 12-Ohm is in parallel to the other 12-Ohm branch then the equivalent of them will be:

Now, the above resistance is in series with the 6-Ohm resistor.

Hence, the total resistance of the circuit is 12-Ohm.
