Description of bipolar transistor

The transistor is primarily used as a current amplifier. When a small current signal is applied to the base terminal of a bipolar transistor, it is amplified in the collector circuit. This current amplification is referred to as hfe or beta and equals Ic/Ib. As with all semiconductors, breakdown voltage of a transistor is also a desi... Read more...
