Turning the potentiometer clockwise increases the conduction angle, delivering more voltage (and therefore more power) to the load. Turning it counter-clockwise reduces voltage smoothly down toward zero. This method is highly efficient because the SCR dissipates very little power itself, keeping the module cool even at high loads.\u003c\/p\u003e\n\n\u003ch2\u003eProject Ideas \u0026amp; Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Speed Control:\u003c\/strong\u003e Regulate the speed of AC universal motors in power tools (drills, grinders, routers) and small appliances.
