Question : 21 of 65

Marks: +1, -0

In the circuit shown below all component ideal, input voltage is sinusoidal. Magnitude of steady state output

V_{o}

is__________ V.

Solution:

The circuit shown is a voltage doubler. So

{V}_{0}=2 {V}_{ {m}}

So the peak value at '

{P}^{'} {m} 2 {Vm}

, Then the voltage across

{C}_{2}

which is

2 {V}_{ {m}}

∴ V_{0}=2 {Vm}

where

{V}_{ {m}}=230 √{2}=325.27 {V}

{V}_{0}=650.5 {V}
