The name of this electronic device is derived from it’s fundamental action transfer resistor.
Working of transistor
- Active mode: Also known as linear mode operation.
- Saturation mode: Maximum collector current flows and transistor acts as a closed switch from collector to emitter terminals.
- Cut-off mode: Denotes operation like an open switch where only leakage current flows.
- Inverse mode: The emitter and collector are inter changed.
