The circuit represents a full wave bridge rectifier when switch \(S\) is open. The output voltage \((\text V_0)\) pattern across \(R_L\) when \(S\) is closed:

1.		2.
3.		4.

The peak voltage in the output of a half-wave diode rectifier fed with a sinusoidal signal without a filter is \(10~\text V.\) The DC component of the output voltage is:
1. \(\dfrac{10}{\pi }~\text V\) 

2. \(10~\text V\) 

3. \(\dfrac{20}{\pi }~\text V\) 

4. \(\dfrac{10}{\sqrt{2}}~\text V\) 

If a full-wave rectifier circuit is operating from \(50~\text{Hz}\) mains, the fundamental frequency in the ripple will be:
1. \(25~\text{Hz}\)
2. \(50~\text{Hz}\)
3. \(70.7~\text{Hz}\)
4. \(100~\text{Hz}\)
