Photo diodes
Why can't the photo diodes produce large amperes of current? are there any large photo diodes producing current more than milli amps??
-
Why star delta starter prefer to D.O.L starter for large motors?
We prefer star delta starter for reducing start voltage but Normally in D.O.L starter-motor is always connected in star - it will also start in reduced voltage.... Explain
