Basically a transistor is nothing but two pn-junctions connected back to back. By examining both the junctions (Emitter-Base junction and Collector-Base junction) with the help of a digital multimeter, we can comment on the functionality of the transistor.The test of the transistor is based on the principle of pn-junction biasing, ...
