Transformers

Q1: When does maximum power transfer happen from the source to the load?

A When the source resistance is greater than the load resistance

B When the source resistance is less than the load resistance

C When there is negligible source resistance

D When the source resistance equals the load resistance

ANS:D - When the source resistance equals the load resistance

We know that transformer is used to transfer power from one circuit to another and also for impedance matching, it happens when "source resistance is equal to load resistance".
