plz do tell me therotically how to make a ckt using a pnp
transistor to operate a 24V relay. push button,diodes,
resistors,capacitor and one pnp transistors are available.
Answer Posted / rahul
connect transistor in emitter follower configurations
means connect E terminal to gnd. connect relay on collector
apply req. biasing vlt. to transistor .
Connect diode parallel to relay to freewheel the energy
stored by the relay coil.
Also used resister to limit the current through base.
