Question
A class A transformer-coupled amplifier uses a $25: 1$ transformer to drive a $4-\Omega$ load. Calculate the effective ac load (seen by the transistor connected to the larger turns side of the transformer).
Step 1
We know that the transformer has a turns ratio of 25:1, which means that the primary side (connected to the transistor) has 25 times more turns than the secondary side (connected to the 4-Ī© load). Show more…
