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.

Which is used for ac to ac convertion?
electrical voltage
What voltage is used in Ireland?
The voltage used in Ireland is 220V AC, at 50Hz.
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.
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.
What is the Symbol used for AC voltage?
a sine wave (~)
What an led accepts whether ac or dc voltage?
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.
Where ac voltage controllers are used?
AC voltage controllers are used for controlling the speed of universal motor or induction motor by changing the firing angle :) -vinodh gav
What voltage is used in most Dell Laptop AC Adapters?
What voltage is used in Dell Laptop AC Adapters depends on in which part of the world the laptop gets bought. Europe for example has a diffrent voltage then the USA.
What will the multimeter show if it is used to measure the voltage of the ac half wave rectified voltage?
rms value of voltage
What mathematical formulas is used to find the average value voltage for an ac voltage?
The RMS value of an AC voltage is VRMS = VPEAK / sqrt(2), where VPEAK = the voltage peak to neutral.AnswerThe average value of a sinusoidal a.c. voltage is zero.
Why do you obtain more dc voltage than ac voltage in power supply design by using transformer?
You don't. Transformers only work with AC voltage. Their input will be an AC waveform, and their output will be an AC waveform. Other electronics are used to convert the stepped down AC waveform from the transformer to DC.
What device is also called a rectifier?
A rectifier is an electronic device that changes an AC voltage to a DC voltage.
