Given:
Vrms=120v
Transformer turns ratio=10:1
Frequency,F(in)=60hz
Calculation:
Secondory Emf=V(in)*(Turns ratio)^-1
=120/10=12V;
Since centre tapped transformer is used,
V2=Emf/2 =12/2= 6V;
Peak voltage=√2*V2=8.48=8.5V
Output Voltage=8.5-0.7=7.8V
The average DC voltage=2V(peak)/π=5.4V
The output Frequency=2F(in)=120hz
