I have a few questions regarding this circuit:
1. There is no step-down transformer used in the circuit, is voltage being dropped? and how (if yes)?
2. On the base of Q1 (BC558) high voltage is applied, why a big resistance is not used here?
3. when the voltage is applied to the transister's base, it must start conducting between emitter and collector. Isn't this transister doing reverse job?
4. Can I use a relay instead of LEDs to run high power AC moter? In this case how much power this circuit will take including relay?
