State two advantages of a triac as compared to an SCR?
triac act as a ac contactor
How you convert 220V ac to 280v DC?

What is the name of the scr or triac triggering system that triggers the output device at the same point on each ac cycle?
Diac
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.
State two advantages of a triac as compared to an SCR?
triac act as a ac contactor
What is the full form of TRIAC?
TRIAC is the word derrived from the 2 words TRIode and AC.
Difference between diac and triac?
The diac and the triac are used to control the AC lines. The difference is that triac are bigger than diac.
What is the ac equivalent circuit for a transistor?
Transistor are DC output, Triac are AC output.
Can you use a rheostat on ac motor?
Yes you can use a rheostat to control the speed of an ac motor as long as it is correctly sized (power). A better way would be to use a triac control.
What component is used as a high power solid state AC switch?
Triac.
What is the frequency of ac in Egypt?
220v 50Hz
What are the applications of a triac?
A triac is a semiconductor-based solid state electronic switch. The main applications are those which require the electronic switching of AC circuits. The switching can go from 100% on to 100% off (or vice versa) or can allow only portions of each AC cycle to pass through, which varies the amount of power supplied to the load. That is how triac-based AC lamp dimmers work.
How can you step down 220v ac to 150v ac?
By using a Variac Transformer
Can an amplifier can be operated on ac supply?
Yes, an amplifier can be operated on ac supply.

What is the main application of a triac?
A triac is a solid state (semiconductor) electronic switch we use in AC circuits. The main applications are those involving electronically switching AC circuits on and off, and in controlling voltage in AC circuits as we see done with AC light dimmers. Certainly there are other applications for the device, but these are the most commonly encountered ones. Electronic dimmers based on a triac can be found in the electrical departments of just about any hardware or home supply store.
