Vedclass · Answer

(A) In the given circuit,switch $p$ is in series with a parallel combination of two switches labeled $q$,and this whole combination is in series with switch $r$.For the current to flow,the circuit must be complete.This requires switch $p$ to be closed,at least one of the switches $q$ to be closed,and switch $r$ to be closed.Therefore,the condition for current to flow is $p \land (q \lor q) \land r$,which simplifies to $p \land q \land r$.Thus,$p, q,$ and $r$ must all be closed.

When does the current flow through the following circuit?
