i want to know how to control the voltage of light bulb 220V using relay ?
if i want to use 1 relay with 12V DC, that means if i give 12V DC, the light bulb is on and when 0V, the light bulb is off.
the questions :
1. if i want to create so much output to light bulb like 50V,60V,70V......220V, how the circuit should be ? can you teach me how ? thanks
2. if i give 8V DC as an TRIGGER on relay, is the light bulb will ON ?
Thanks if you can teach me more.
