A diode is a "one-way valve" that allows electrical current to flow in only one direction. A diode placed in series between an AC voltage source and a resistive load will allow current to flow through the load in one direction and block the current when the polarity of the AC voltage changes.

Can led works as ac sources?
No. An LED (light emitting diode) allows current to flow in one direction, thus it cannot alternate as is implied by "an AC source". ANSWER: YES they can. Any diode can work with AC They can work from AC line directly. My overhead light in my kitchen are across 120 AC now for 8 years. But then again I know what I am doing
What is N4001 diode?
1.0A RECTIFIER diode used to convert ac power to dc power
What happen if all the diode in bridge rectifier is reversed?
it will work as a rectifier . because the AC current to be rectified will not be effected by this change. the out put DC polarity will be changed.
How can we Diode can be used as a rectifier?
A diode is used to stop the negative voltage swing in an AC signal, so you only get the positive portions.diode-rectifier
Can you install a diode to allow 24 volts AC to flow in one direction but not allow the flow of 24 volts AC to flow in the opposite direction?
Diodes convert AC into DC by allowing current flow in one direction only. Since AC is alternating between plus and minus it is not possible to use a diode to allow AC to flow in one direction and not in the other direction.
What is ac resistance of a diode?
ratio of ac voltage applied across the diode to the ac current flowing through it

Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
How do you find the ac resistance of a diode?
The ac resistance of a diode is found using the equation: (The change in Vd)/(The change in Id) An easier was is to use the Equation: 26mV / Id. This is a general form as the ac resistance of a diode change as the temperature changes.
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 is N4001 diode?
1.0A RECTIFIER diode used to convert ac power to dc power
What happens when you connect 230V ac supply directly to a diode?
You get a violent explosion as the diode vaporizes.
How do you connect a diode across a ac coil?
You mean ac coil, the secondary coil, of a transformer? Then for the purpose of rectification, that is , for changing ac into dc, a diode is connected in series with the secondary coil of the transformer.
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 device changes ac to dc in an alternator?
diode
How does the ac resistance of a diode change as the voltage increases?
When the voltage increases the temperature in the diode also increases. When the temperature in the diode increases, the resistance decreases.
Which diode are usd are rectifying ac into DC?
Junction diodes are used for rectifying ac into dc.
