Given a battery, a switch and an electric lamp,how can a NOT gate be constructed?

Text Solution

Verified by Experts

In this case, switch is the input and electric bulb is the output, because when the switch is made 'on' or 'off' then the lamp goes 'off' or 'on' respectively. The circuit shown in Fig. 2.33, is a NOT gate circuit. When the switch the switch A is off, current flows through the lamp Y and it glows. When the switch is on, the entire current passes through the arm of the switch. As a result. the bulb extinguishes. (To avoid short-circuit a low value resistance may be connected with the switch A ) .
