solid-state relays that are intended to connect alternating-current loads to the line use a device called a .

TRIAC.When triggered, a TRIAC is a three-terminal electronic component which conducts current from either direction.What is TRIAC ?Because the triac can be switched "ON" by either a positive or negative Gate pulse, regardless of the polarity of the AC supply at the time, it is the most commonly used semiconductor device for switching and power control of AC systems.TRIAC. DIAC stands for "Diode for Alternating Current." TRIAC stands for "Triode for Alternating Current." It is an alternating current diode that allows current to flow in both directions when the applied voltage exceeds the break overvoltage.TRIAC is widely used in applications where AC power must be controlled, such as ceiling fan speed regulators and AC bulb dimmer circuits. Let's take a look at a simple TRIAC switching circuit to see how it works.To learn more about TRIAC refer to :https://brainly.com/question/14567599#SPJ4
