The symbolic form of the following circuit is (where and $s_{2}$ closed respectively)

The symbolic form of the following circuit is (where and $s_{2}$ closed respectively)
  1. $(p \wedge q) \wedge(\sim p \wedge \sim q) \equiv \ell$
  2. $p \vee[q \wedge(\sim p \wedge \sim q) \equiv \ell$
  3. $\mathrm{p} \wedge[\mathrm{q} \wedge(\sim \mathrm{p} \wedge \sim \mathrm{q}) \equiv \ell$
  4. $(p \vee q) \vee(\sim p \wedge \sim q) \equiv \ell$

Solution

Let $\mathrm{p}$ : the switch $\mathrm{S}_{1}$ is closed $\mathrm{q}$ : The switch $\mathrm{S}_{2}$ is closed $l:$ The lamp Given circuit can be expressed as $(p \vee q) \vee(\sim p \wedge \sim q)$
