A: A LED is a diode that emit photons when exited with enough current and/or voltage. it does not care where the source come from. for AC IT WILL WORK PROVIDED A SERIES DIODE IS ADDED that is there to prevent the led from burning up when the reverse voltage exceed the saturation current . these devices have a very low reverse voltage breakdown limitation and if they breakdown usually the power dissipation will be exceeded and blow up.

Is DC is at low voltage than ac?
There's no correlation between the voltage, the current, and whether the source is AC or DC.
You are wiring a LED lamp through a transformer you have a polarized plug and you know positive and negative The transformer is marked live and neutral Does live correspond with positive or negative?
LED's are DC voltage. Transformers are AC voltage. There is no positive or negative on AC voltage. You would need a diode to change the AC to DC, then there would be positive and negative voltages.
ABS sensor produce AC voltage or DC voltage?
AC !
How do you convert 23 voltage DC to 230 Voltage AC?
How do you convert 23 voltage DC to 230 Voltage AC?
When was Voltage AC created?
Voltage AC was created on 2004-12-14.
Why ac voltage varying?
AC voltage is varying because it is sinusoidal in nature
How do you test for fluctuating line voltage in the electrical supply to a motor?
This depends on whether the voltage is AC or DC but an oscilloscope is the tool of choice for seeing voltages and how they change with time.
What is the voltage for a printer?
Most of the printers offered in the USA have a voltage of 110V AC input and 8V AC output, whereas the printers offered in the Europe have input voltage of 220V AC and output voltage of 8V AC.
Is tranformer used to increase or decrease AC voltage?
The function of any transformer is to change one AC voltage value to another AC voltage value. A step down transformer will transform a higher AC voltage to a lower AC voltage. A step up transformer will transform a lower AC voltage to a higher AC voltage. The transmission of electrical power uses both of these types of transformers. From the generation station the voltage is stepped up to a very high transmission voltage and at the end of the transmission line it is stepped down to a voltage that consumers can utilize.
Led can be used also in ac voltage?
A: LEDS are basically a diodes.So yes they can be strung right across the AC line. Unfortunately the reverse voltage is very low and tend to leak at hi voltage. the design should provide protection for the reverse voltage with resistance across each to equalize the leakage current otherwise it will work only once.
How does capacitor discharge while ac supply is on?
For part of the AC voltage wave, the capacitor will be above the source voltage, and will discharge until the AC voltage wave increases above the capacitor's stored voltage.
How does an led light bulb work?
LED's (Light Emitting Diodes) work on DC current, not AC, so the AC needs to be stepped down to an appropriate voltage via a transformer (probably only a few volts), converted to DC via a rectifier and filter (to smooth out the ripple current). there are a constant driver in side the 120V AC led light bulb , this driver transfer the AC to DC, so the led could work with DC.
