WebFor this Vbe should be 0.7 V. So you can calculate the current flowing through Rb/base now. You know beta already, so you can calculate the collector current, therefore the collector emitter voltage. Based on our initial assumption, the transistor is in active mode. WebThe entire normal range of silicon transistor operation involves a change in base-emitter voltage of only about two-tenths of a volt. This is because the base-emitter diode is forward biased.One of the constraints on transistor action is that this voltage remains at about 0.6 volts (often referred to as the diode drop). A small change in V BE can produce a large …
