Answer / dhafer faisal

Answer:
Output d.c. voltage, Vdc = 50 V
Diode resistance, rf = 25 Ω
Load resistance, RL = 800 Ω
Let Vm be the maximum value of a.c. voltage required.
∴ Vdc = Idc × RL
= π( )

∴ Vm = π 825 50

Hence a.c. voltage of maximum value 162 V is required.

If input frequency is exceed the slew rate the output will be a. Distorted b. No Output c. Not distorted d. Amplified
