The Maximum efficiency of the transformer-coupled Class A amplifier is 50%.
Efficiency = (output Voltage/input voltage) x 50%.
= (10/15) x 50%.
= 33.33%.
Efficiency = (output Voltage/input voltage) x 50%.
= (10/15) x 50%.
= 33.33%.

%n = 50 * ((VCEQ - Vp)/(VCEQ + VP)).
= 50 * ((15-10)/(15+10)).
= 33.33 %.
= 50 * ((15-10)/(15+10)).
= 33.33 %.

It should be pk-pk.
[(10/2)/15]100 = 33.3%.
[(10/2)/15]100 = 33.3%.
