If a 169.7 V half-wave peak has an average voltage of 54 V, what is the average of two full-wave peaks?
119.9 V
108.0 V
115.7 V
339.4 V

Half wave rectifier.
Vdc = Vpeak/pi.

For full wave rectifier.
Vdc = 2*Vdc (half wave rectifier).
54*2 = 108.

In the question they ask for two full wave's average peak value. So it will be 54*4=216. Am I correct?

Vm/π :- Half wave avvg voltage.

Full wave avrg, voltage=2Vm/π.
So 2*169.7/π
= 108.

54 = vm/π
vm = 54*π
fwr = 2*vm/π
= 2 * 54*π/π = 2 * 54 = 108v.

169.7(54).
399.4(?),
?=54*399.4/169.7 = 108.0v.

Since the PIV of a half-wave is Vm and is the same 169.7V so finding the PIV of a full-wave will be 2Vm where Vm is 54v.

So, the solution becomes 2(54) = 108.0V.
