SSR using Triac and MOC3041
A TRIAC (Triode for Alternating Current) is a three-terminal, bidirectional semiconductor device used as the primary switching element in most AC solid-state relays (SSRs). It functions as an electronic switch that can conduct current in both directions, making it ideal for controlling alternating current loads such as lamps, motors, or heaters. Structurally, a TRIAC behaves…
