Such combination of capacitors is very essential. There are two methods of combination of capacitors Capacitors are connected in parallel combination to achieve a higher capacitance than what is available in one unit. Conditions for parallel grouping Voltage rating of capacitors should be higher than the supply voltage Vs.
We’ll also look at the two main ways we can connect capacitors: in parallel and in series. By the end, you’ll see how these connections affect the overall capacitance and voltage in a circuit. And don’t worry, we’ll wrap up by solving some problems based on combination of capacitors.
Fundamental capacitor circuit 90 degrees out of phase. It is said that the current leads the voltage by 90 degrees. The general plot of the voltage and current of a capacitor is shown on Figure 4. The current leads the voltage by 90 degrees. Xc has the units of Volts/Amperes or Ohms and thus it represents some type of resistance.
The output capacitor is outside the loop and so has no bearing on the phase shift around the loop or the oscillation frequency. However there will be some phase shift across that capacitor and the amount of phase shift will depend upon the size of the capacitor and the size of the amplifier's load resistor.
If different voltage rating capacitors have to be connected in series, take care to see that the voltage drop across each capacitor is less than its voltage rating. Polarity should be maintained in the case of polarised capacitors. Series combination of capacitors is shown in the figure below
CT = C1 + C2 + C3 The necessity of grouping capacitors in series is to reduce the total capacitance in the circuit. Another reason is that two or more capacitors in series can withstand a higher potential difference than an individual capacitor can. But, the voltage drop across each capacitor depends upon the individual capacitance.
