How does a transistor work as a switch and amplifier ... If the base voltage (bias voltage) is too low, practically no current can flow through the transistor and it effectively operates as a switch that is opened. Too high and the transistor hits saturation, which is where further increase of the bias voltage has little or no effect on the current flow through the transistor. How to Use an NPN Transistor as a Switch – Fiz ix Biopolar junction transistors are current controlled, meaning a current from the collector to emitter only flows if there is also a small current flowing into the base. This is the essence of how the switch works. Flip Flop Circuit (Transistor Transistor SR Latch Circuit ... This is a dual Transistor circuit, which means that it uses two Transistors. As it is based on Transistors, you'll need to know what they are and how they behave. Transistor as a switch slideshare.net • Transistor Switch Base Resistance 10.
