WebThe impedance of a resistor stays constant with frequency. For a capacitor, its impedance get smaller and smaller as frequency goes up. If R and C are in series, at 0 frequency the capacitor has infinite impedance (1/jwC = infinity), so it acts like an open circuit (we say a capacitor blocks DC current). The Resistor will have zero current and therefore zero voltage. WebAnd you will not have any voltage drop across a resistor with zero current flowing through it. I think you might be getting a little confused between amps and volts. for instance, adding 5A through a resistor does not mean you added 5v across it (unless you have a very heavy duty 1 ohm resistor) Voltage(E) = current (I) times resistance (R)

WebWhen the frequencies are lower, the resistance between the emitter and the ground is no longer only r e but RE+re and therefore the voltage gain decreases to AV= (RC//RL)/ (RE+re). There is another type of capacitors …
