Web945K views 4 years ago The Learning Circuit Rather than using a physical, mechanical switch, a transistor can act as an electronic switch, using signals to turn it on or off. Karen goes over what... 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. raw theraphee https://vipkidsparty.com
