P POWERPRATIK New Member Apr 2, 2010 #1 Hello Dear....... I have a project to control the intensity of bulb through triac. I have gate pulse to fire the triac. Circuit is like below: Phase to triac(switch) to bulb to neutral. When i give gate pulse to triac, triac is on and the bulb is gettig on also the i/p voltage is vary. i want to see the i/p waveform on CRO, but it is not measured..... it's a problem.... How to see the i/p waveform on CRO?
