LED means Light Emitting Diode A diode only lets current through in one direction - that's what they do.
AC means Alternating Current - the current goes from plus to minus and back again 50 or 60 times a second (depending on the standard)

What is the different between ac dc motors?
DC Motor works on DC source and AC motor works on AC source
What kind of electricity used for LCD and LED means ac or dc?
LCDs are driven with AC, to prevent electrolytic damage to the thin transparent electrodes. LEDs are driven with DC.
How capacitor works with ac supply?
Ti controls the capacity of power our machines use
Fan works on ac or DC?
It depends on the motor. The fan is driven by an electric motor, and it can use a dc motor (as in a car) or an ac motor (as in a house). They are not interchangeable.
Does electrical transformer use a DC or AC source?
A transformer is a device to convert high voltage AC to low voltage AC & vice-versa. It works on the principle of induction. Since induction occurs only in an AC supply, a transformer cannot work on DC.. So, it is not possible to convert DC supply to AC using transformer. You would need an inverter to convert DC to AC.
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
Can ac power a 9-31V LED light?
With the proper AC to DC adapter, you can power the LED.
What is the different between ac dc motors?
DC Motor works on DC source and AC motor works on AC source
Where does AC works?
Indoor and outdoor
Who had more number 1 hits acdc or led zepplin?
Ac/ dc
Do lightbulbs in homes operate on AC or DC voltage?
The bulb works under AC
Can a dc motor works in ac current?
no
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.
How does an 120VAC 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.
Is wattmeter is work on ac or dc?
this works with both.
What is the room size that the LG 7000 / 3850 - AC/ Heater works better in.?
This AC/Heater unit works best for a room size of 10 x 15.
What is ac drive and how it works?
An AC Drive used for a speed control of a motor by using vary frequency.
