Hello All,
I am beginner in electronics I wish to know why do we need to do DC analysis and ac analysis of a circuit? As a rule , what component or node we must short to gnd for ac equivalent circuit? Then for DC analysis, what are the rule of thumb? Please let me know in step by step. Or any online document you can share
Also if input is voltage source or current source which I do not know if it is ac or dc type, what should I do with them when I draw an ac or dc equivalent circuit?
Kindly help thanks
Jason
