Which resistor is connect 1.5 volt led to series 220v ac?
Typically, a 100 ohm resistor is used to connect a 1.5 volt led to a series 220v ac adapter. Many LEDs can be connected into a string using the resistors.
What is the frequency of ac in Egypt?
220v 50Hz
How can you step down 220v ac to 150v ac?
By using a Variac Transformer
How you convert 220V ac to 280v DC?
NAVEED45
Why is there no LED's that run from AC?
There are LED's that run on AC. Remember that an LED is still a diode, and it conducts in one direction only. You can place an LED and a resistor across an AC source, and it will work, so long as you consider both the forward bias condition and the reverse breakdown voltage.Also, there are some dual LED's mounted in one package that are wired back to back. Applying current in one direction makes them glow red, while applying current in the other direction makes them glow green. If you apply AC to them, they glow both red and green, which is yellow. (Colors, of course, vary, depending on the particular diode.) And, if you want to get fancy, you can pulse-width modulate the current and effectively modulate the color.
Is it possible to built a device which takes AC 1P 220V as input and gives 220V 3P output?
Yes
Can triac be operated at 220V ac suppply?
If it is rated to do so, yes.
What plug socket and voltage does Iran have?
Round 2-pin; 220V AC
What voltage is used in Ireland?
The voltage used in Ireland is 220V AC, at 50Hz.
How do you calculate ampere given 220v AC 40KW?
The formula you are looking for is I = W/E
How you convert the 220v AC to 220v DC?
You can make this conversion if a full wave bridge rectifier is used. Make sure that the diodes are rated for the voltage that is being used.
Which device you use to increase voltage from 220V to 11000V?
If it is AC, a transformer. If it is DC, a motor generator.
