Emitter Capacitor Short Circuit Tutorial

The emitter is connected to zero volts and there is an increased emitter/base forward bias.

Base and collector currents increase.

There is more current through R1, a higher voltage drop across it, and a lower base voltage.

Since the collector current is higher there will be a larger voltage drop across R3. The collector voltage will  be lower than normal.

The emitter voltage will of course be zero.

If the capacitor goes open circuit, the dc voltages will remain at their normal values. However, the gain will be much reduced.
