Using LTSpice
LTSpice is a software for circuit analysis. I'll try to explain how this powerful software can be utilized to solve circuit problems quickly and easily. I'll start with simple transient analysis.
The question is why LTSpice? There are many circuit-analysis software available, however I suggest to use LTSpice for the following reasons:
1. It is free
2. Very convenient to use
3. Fast, and very little simulation error
First step, Download LTSpice from the following link
