Logic Gate NOT

Basic NOT gate NOT gate is inverting circuit / inverter. Equivalent circuit is an electrical circuit such as Figure 3.8 below. When the switch A is connected (on), then the light will die. Conversely when the switch A is disconnected (off), then the light will turn on. So it can be concluded that there will be output Q = “1” only when input A = “0”.
