An NPN transistor symbol shows an arrow from the base to the emitter. This means that the current flows from the collector through the base into the emitter. WebSep 9, 2024 · A transistor works in two modes – saturation and cutoff. When it works as a switch, it turns off when it is in cutoff mode, since no collector current flows through it, and it turns on when working in saturation mode. Collector current is generated when an input signal is present at the base; this is when the transistor is ON. chromium type 2 diabetes
