Answer
# 2		 
scr means silicon controlled rectifier.ordinary diode   
rectifiers are used for constant dc output voltage.but 
scr's are used for variable output dc voltage which 
depending on the gate triggering. once scr is fire or ON 
the gate voltage is not neccessary. off the scr is possible 
only disconnect the anode to cathode voltage.
