Meanwhile, the basic concept behind the operation of a transistor as a switch relies on its mode of operation. Scope traces are similarly referred to by channel and voltage / current. Determine Ra and Rb to meet the amplitude and time constant specifications. 1 - small signal NPN transistor (2N3904). It is a very common mistake to switch the emitter . Common emitter amplifier develops voltage output due to the current through the load resistor. The extra power comes from an external source (the power supply). Return to Introduction to Electrical Engineering Lab Activity Table of Contents We control traditional switches manually by applying a mechanical force. The above argument makes it intuitively clear that the emitter current is greater than the base current (also see equation #3 below). The circuit can be a constant current source or a constant voltage source. Transistor As A Switch Using a transistor as a switch is the simplest application of the device.
