Solid State Relays Understanding Operation Testing with Multimeter Live Demonstration

Solid State Relay (SSR) Circuit using Two MOSFETs SSR or Solid state relays are high power electrical switches that work without involving mechanical contacts, instead they use just a couple of solid state semiconductors like MOSFETs for switching an electrical load, smoothly, and with high efficiency. SSRs can be used for operating high power loads, through a small input trigger voltage with negligible current. These devices can be used for operating high power AC loads as well as DC loads. Sol
