This circuit shows the working
This circuit shows the working of a logical AND gate using two transistors.
When both the switches are open, there is no current flowing through the transistors and hence the output is LOW. In this state, the LED is OFF.
When one switch is closed and the other is open, the respective transistor is either ON or OFF. However, the current cannot flow through the transistors as they are connected in series. Hence the output is LOW. Again, in these states, the LED is OFF.
When both the switches are closed, both the transistors are ON and the current flows through them. Hence the output is HIGH and the LED turns ON.
