How Does NPN Transistor Work?
When a voltage is applied to the base-emitter junction, it forward biases the junction, allowing a current to flow from the emitter to the base. This current flows through the base and into the collector, where it is amplified and flows to the output circuit. The transistor can be used as an amplifier or a switch, depending on the biasing configuration.
