Answer:
) The total secondary voltage in a center-tapped full-wave rectifier is 125 V rms. Find the rms output voltage, assuming that the diode drop is 0.7V. b) A certain power-supply filter produces an output with a ripple of 100 mV peak-to- peak and a dc value of 20 V. Find the ripple factor.

Given:
The total secondary voltage in a centre tapped full wave rectifier is 125 V rms.
To Find:
the rms output voltage is
Explanation:
- Center-tapped full-wave rectifier with a transformer turns ratio of 2.
- In any case, the output voltage of a center-tapped full-wave rectifier is always one-half of the total secondary voltage lesser the diode drop, no matter what the turns ratio.
Vout = (Vsec/2) //so … 125 / 2 = 62.5
Answer = 62.5
