The DC characteristics of the base-emitter junction are displayed, both the base-emitter forward voltage drop and the base current used for the measurement.. The forward

It is important to note that the DCA Pro does not perform the base- emitter voltage drop tests at the same base current as that used for the current gain

BJTs are used to amplify current, using a small base current to control a large current between the collector and the emitter.. This amplification is so important

In this circuit, the base of the BJT serves as the input, the emitter is the output, and the collector is common to both input Bipolar junction transistors (BJTs) are three

Essentially any additional voltage in the emitter circuit other than the balanced out voltage drops of the silicon diode and the base-emitter junction will be transfered to
