A TRIAC is a three-terminal semiconductor component that conducts current in both directions when triggered. It is often used to control high-power AC currents, both as a switch and for "dimmers" for controlling lamps or electric engines.

Resistance issue in a triac-optocoupler switch
I have tried many resistors (calculated myself) to limit current in the optocoupler and triac, but failed to carry the load for a long time. … At one time either resistor get burned or triac gets too hot. Kindly suggest what resistance I should use in the resistors with '?'. Any other suggestions are also welcome. …
