Circuit Theorems in AC Analysis - Engineering

Q1:

The Norton equivalent current is

A the current through the load

B the open-current from the source

C the short circuit current

D none of the above

ANS:C - the short circuit current

Any linear electrical network with voltage and current sources and only resistances can be replaced at terminals A-B by an equivalent current source INO in parallel connection with an equivalent resistance RNO.

This equivalent current INO is the current obtained at terminals A-B of the network with terminals A-B short circuited.
