Bipolar Junction Transistor (BJT): What is it & How Does it Work
WebThe input circuit of BJT is forward biased. Hence BJT has low input impedance. FET is a voltage driven device. BJT is a current operated device. In BJT the output current is controlled by the variations in the input current. It produces a current gain. But in a FET, a small voltage at its gate controls the drain current. WebMay 22, 2024 · The voltage from base to emitter has a − to + polarity, meaning it is a rise of 0.7 volts. Therefore The voltage across is the difference between and . This is the same value we arrived at using method one, so the collector current must be the same at 1.24 mA. To find we also have options. One path is to use a slightly modified Equation . in accounting a debit is increase or decrease
