Mention how NPN and PNP transistor works?



In a circuit when NPN is used, 
  • No current flowing from A to D = No flow from X to Z
  • Current flowing from A to D = Current allowed to flow from X to Z 
When PNP is used, 
  • No current flowing from A to D = Current is allowed to flow from X to Z
  • Current flowing from A to D = No current flow from X to Z
