Answer 1

The circuit is of or circuit is used to amplity sinusoidal rottage waveform. Sketch on the axes provided general Shape of the Nottages Vin, ve, 2 and Vout 1 Vin D a noul Answers :- This circuit is a common-emitter amplifier Rote of input capacitor :- This capacitor Couples the signal to the base a transistor. This is an electrolytic capacitor of value approximately louf. In the absence of this capacitor the source resistance will come in parallel. This the capacitor allows oney a.c Signal to flow. The sinusoidal Source voltage causes the basse rottage to van Enusoidally above and below its de bica lovel, VBg

Now, the instantaneous a point moves towards. of base curent increases then collector current increasser for a fixed collector resistor, when collector current increases, collector voltage Contput) decreases. output is inverted to input.
