Circuit Diagram Of And Gate Using Transistor. The current is dropped across the emitter resistor. Initially both the switches are in off state so none of the transistor.

The current is dropped across the emitter resistor. The transistors used in this tutorial are bc547 npn transistor and were added with all the above mentioned components in the circuit as shown below. When the switch is closed a small current flows into the base b of the transistor.
The transistors used in this tutorial are bc547 npn transistor and were added with all the above mentioned components in the circuit as shown below.
In the above circuit when a or b or both a and b are grounded or at 0v potential transistor t 1 or t 2 or both t 1 and t 2 are in off condition respectively. The current is dropped across the emitter resistor. The base of both the transistors act like inputs and one of the emitter of either of the transistors is used to derive the output. This hardware schematic can resemble the circuit diagram shown below for easy understanding.
