If the symbolic form of the switching circuit is [ pv ( p q )] v q , then the current flows through the circuit onlyif

Options

  1. Airrespective of status of the switches
  2. Bone switch should be open and other should be closed
  3. Cboth switches should be closed
  4. Dboth switches should be open

Correct answer

A. irrespective of status of the switches

Step-by-step solution

[ p (p q)] q=[( p p) ( p q)] qE[T ( p q)] q ( p q) q p ( q q) p T T This shows that current flows irrespective of status of the switches.
