What is the ac equivalent circuit for a transistor?
Transistor are DC output, Triac are AC output.
What is a gateless triac?
A gateless triac is a diac. It is often used in the gate circuit of a triac to balance out the firing voltage for the triac in both quadrants, so that there is no DC offset in the controlled load. This is because, while the gate trigger voltage is often asymmetric in the two quadrants, the M1/M2 breakdown voltage is often symmetric.
Can you use Diac and Triac for dc supply?
The diac conducts in both directions at approximately the same voltage, making it unsuitable in an AC to DC supply. The triac also conducts in both directions, based on a gate voltage which is slightly different in the two usable quadrants. That is why the diac is often used to trigger the triac - it makes the two conduction cycles more symmetric. In both cases, the diac/triac does not make sense for an AC to DC supply, but it works well in an AC voltage regulator, such as a lamp dimmer or motor speed controller.
What is the full form of TRIAC?
TRIAC is the word derrived from the 2 words TRIode and AC.
What is an electrical switch that opens and closes under the control of another electrical circuit?
If it is a physical switch, this is called a "relay" or a "contactor". If it is a semiconductor device, it is typically a triac, SCR or a thyristor.
What does the term 'triac' means?
A "triac" is a type of thyristor designed for electronic control of the current supplied to a circuit, used especially in dimmers for lighting systems.
What is the ac equivalent circuit for a transistor?
Transistor are DC output, Triac are AC output.

This is because, while the gate trigger voltage is often asymmetric in the two quadrants, the M1/M2 breakdown voltage is often symmetric.
What is the population of Triac-Lautrait?
Triac-Lautrait's population is 454.
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.
Why we don't use triac in case of ac controlled rectfier rather than scr?
A TRIAC does not have a symmetrical turn-on point in the opposite quadrant. This will introduce a DC bias, which you probably don't want. You can use an SCR, and then add diodes to allow it to operate in the opposite quadrant, or you can use two SCR's. Alternatively, you can use a DIAC in the TRIAC's gate circuit to balance the turn on point.
What is the area of Triac-Lautrait?
The area of Triac-Lautrait is 6,400,000.0 square meters.
How does triac works?
Triac is Three Layered Device . Emitter ,Collector and Gate

State two advantages of a triac as compared to an SCR?
triac act as a ac contactor
