it clips all the bottom voltage off the sine wave,to get steady dc voltage you will need to clean up the ripple to get good voltage regulation

A diode does not change AC to DC, but it does allow alternating current to flow in only one direction. A diode (or often 2 or 4 diodes) with a filter can be used to rectify AC into DC.

What property of a diode enables it to convert ac to dc?
A diode allows electrons to pass only in one direction. During the negative half cycle of an alternating current the diode will not allow electron current to pass. It is like a one way valve. This property of diode enables it to convert AC into pulsated DC
What do you mean the word diode which is used in electronics?
Diode is a Two terminal device which allows flow of curent in forward direction that means it converts DC to AC
How does pn junction diode can be used as an electronic switch?
A diode allows current to flow in only one direction. If the current is flowing, the diode has a low resistance and it behaves like a wire or a switch in the on position. If the voltage across the diode is reversed, no current flows and the diode has a very high resistance. It behaves like a switch in the off position. DC voltages are used to switch the diode on or off. The signal that is being switched is usually an AC audio or radio signal. Capacitors block DC but pass AC signals. By combining diodes and capacitors, the AC and DC signals are kept separate and the switch can be built.
What is the behavior of a forward and reverse biased diode?
Forward Resistance:def: It is resistance offered by diode to the forward bias is known as forward resistance.This resistance is not the same for the flow of DC as for the changing current. Accordingly this resistance is of two types :1. DC FORWARD RESISTANCE.2. AC FORWARD RESISTANCE.1. DC forward resistance: It is the opposition by diode to the DC. It is measured by the ratio of DC voltages across the diode to the resulting DC current through it.2. AC forward resistance: It is the opposition offered by the diode to the changing current. It is measured by the ratio of change in voltage across diodes to the resulting change in current through diode. The AC forward resistance is more significant as the diodes are generally used with alternating voltage.Reverse Resistance:def: The resistance offered by the diode to the reverse bias is known as Reverse Resistance. It can be DC reverse resistance or AC reverse resistance depending upon whether the reverse bias is direct or changing voltage. Idealy the reverse resistance of a diode is infinte however in practice the reverse resistance is not infinite because for any value of reverse bias, there does exist a small leakage current. It may be emphasized their that reverse resistance is very large compared to the forward resistance.These Definitions are from PRINCIPLES OF ELECTRONICS by V.K MEHTA and ROHIT MEHTA
When connecting power supplies that convert ac to dc note that the diode will determine the load polarity?
This statement is correct
What is bridge rectifire?
A four diode circuit to change ac to dc
Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
Which diode are usd are rectifying ac into DC?
Junction diodes are used for rectifying ac into dc.
How do you conyert AC to DC?
You rectify AC voltage through a diode bridge to convert it to DC.
Are diodes only used in a dc circuit?
There are lots of diodes - a "diode" is simply a device that has two electrical connections.If you refer specifically to the rectifying diode, it is used to convert AC current to DC current - so, it is used in a circuit that has BOTH AC and DC.
How diode convert pure ac to pure dc?
You can't convert ac to pure dc with diode only. The easiest way to convert ac to dc by with diode is by using rectification, it consist of at least 2 diodes (half wave rectifier) and (capacitor is to "smoother" the wave).
What is the difference between diode and converter?
Diode: Which allows power in one direction or which converts AC to dc . Converter: Which converts DC to DC
What device changes ac to dc in an alternator?
diode
Can diode work on ac power supply?
diodes conduct electricity in only one direction but as ac change direction in each of its cycle diodes can only conduct half of its cycle which will give u a pulsating dc. but if dc is mixed with ac and if it can put whole of its cycle in positive direction diode can conduct ac. so diodes are usually used to produce dc from ac.
What are the roles of a diode and a capacitor in an AC-DC converter?
An AC-DC converter you can operate a device on AC instead of batteries. ~bobbyjack~ : D
What is N4001 diode?
1.0A RECTIFIER diode used to convert ac power to dc power
How do you test a diode bridge?
How to test a diode bridge ? Diode bridge is a device is used to convert an AC signals (say AC voltage) to DC output (say DC voltage). So, to test it, you can apply a AC voltage v = Vm Sin (wt) at its 2 inputs and measure DC output voltage Vdc.
