Vedclass · Answer

(A) The circuit consists of two main parallel branches. Branch $1$ contains switches $s_{1}$ and $s_{2}$ in series,represented by $(p \wedge q)$. Branch $2$ contains switch $s_{1}'$ (which is $\sim p$) in series with a parallel combination of $s_{2}'$ $(\sim q)$,$s_{1}$ $(p)$,and $s_{3}$ $(r)$. This parallel combination is $(\sim q \vee p \vee r)$. Thus,the symbolic form is $(p \wedge q) \vee [\sim p \wedge (\sim q \vee p \vee r)] \equiv \ell$.

The symbolic form of the following circuit is (where $p, q$ and $r$ represent switches $s_{1}, s_{2}$ and $s_{3}$ which are closed respectively):
