How many capacitors are connected in series?

Figure 8.3.1 8.3. 1: (a) Three capacitors are connected in series. The magnitude of the charge on each plate is Q. (b) The network of capacitors in (a) is equivalent to one capacitor that has a smaller capacitance than any of the individual capacitances in (a), and the charge on its plates is Q.

Why does a capacitor discharge at its own pace?

Or is the discharging process independent of the presence of other capacitors, and it will discharge at its own pace. The rate of discharge of each capacitor has to be the same since for a series connection the current in each capacitor is the same. The C in the RC constant for the circuit is the equivalent series capacitance.

What if two series connected capacitors are the same?

Then we can see that if and only if the two series connected capacitors are the same and equal, then the total capacitance, CT will be exactly equal to one half of the capacitance value, that is: C/2.

How do capacitors in series work?

When adding together Capacitors in Series, the reciprocal ( 1/C ) of the individual capacitors are all added together ( just like resistors in parallel ) instead of the capacitance’s themselves. Then the total value for capacitors in series equals the reciprocal of the sum of the reciprocals of the individual capacitances.

Why do all capacitors have the same charge?

Charge on this equivalent capacitor is the same as the charge on any capacitor in a series combination: That is, all capacitors of a series combination have the same charge. This occurs due to the conservation of charge in the circuit.

What is the total capacitance of a circuit containing capacitors in series?

Then to summarise, the total or equivalent capacitance, CT of a circuit containing Capacitors in Series is the reciprocal of the sum of the reciprocals of all of the individual capacitance’s added together.
