Average voltage;
Vavg=Vmax/π=12v ----> 1.
We found rms voltage = Vrms=Vmax/2 ------> 2.
From equation 1 Vmax=Vavg x π
= 12 x π
= 12 x 3.14,
= 37.68.
Applying equation 2 Vrms=Vmax/2.
= 37.68/2 .
=18.84.
Vavg=Vmax/π=12v ----> 1.

Vav = 0.636Vpk.
Vpk = Vav/0.636 = 12/0.636.
=.18.867925,
Vrms = Vpk/√2.
= .13.34.
Vpk = Vav/0.636 = 12/0.636.
=.18.867925,
Vrms = Vpk/√2.
= .13.34.

Half wave
Vavg=vm/π
Vm=vavg*π
Vm=12*π
= 37.69.
Vrm=vm/2.
= 37.69/2,
=> 18.84.
Vavg=vm/π
Vm=vavg*π
Vm=12*π
= 37.69.
Vrm=vm/2.
= 37.69/2,
=> 18.84.
