Node Voltage Method - Example 6 (Trick: How to handle CCCS)

This video shows how to apply Node Voltage method to solve a circuit containing a Current Controlled Current Source (CCCS). CCCS can never cause a super node to be formed. The circuit equations are solved using Mathematica. The power associated with the CCCS is also determined. It also shows how to verify the solution using PSPICE and LTSPICE. The PySpice (Python) code to simulate the circuit is provided in the comments section below.

The video is organised as follows:
(00:00) [1] Setting up the problem
(02:10) [2] Writing circuit equations
(05:45) [3] Mathematica solution & CCCS power
(07:53) [4] PSPICE solution
(08:34) [5] LTSPICE solution
