Concept of Open Circuit and Short Circuit 

Open Circuit:
The open circuit voltage is nothing but a potential/voltage difference measured between two terminals when no current is flowing through those terminals.

  • An open circuit is defined as an electric circuit in which current does not flow.

  • An open circuit occurs when a circuit is broken from some point.

  • An open circuit is where there is no current flow and voltage tends to infinity.


Short Circuit: 

  • The short circuit current is the tendency of a circuit where current flows when the terminals are forced to have zero voltage/potential difference.

  • The short circuit occurs when some low resistance path occurs between two points.

  • A short circuit is where the voltage tends to zero and current to infinity.
