Frequently asked questions
2N2222A is an NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to the base pin termiter.
Motor Control: The 2N2222A transistor can be used to control the speed and direction of DC motors by controlling the current flowing through the DC motor. Power Supply Circuits.
A transistor consists of 2 PN diodes connected back to back. It has 3 terminals namely emitter, base, and collector. The basic idea behind a transistor is that it lets you control the flow of current through 1 channel.
A transistor is a 3-terminal semiconductor device that can be used as a switching or amplifier. The transistor as a switch is used to turn ON-OFF a circuit diagram. The transistor as an amplifier is used to amplify the voltage or current flow.
1 of the most fundamental applications of a transistor is using it to control the flow of the power supply to another part of the circuit. using it as an electric switch.
