Capacitance in Series: Questions for David

In summary, the conversation discusses the concept of capacitors in series and the relationship between charge and voltage. It is mentioned that the charge must be equal on all plates of the capacitors in a series connection, but there is confusion about how this is possible for the node between the two capacitors. The conversation also touches on the idea of displacement current and how it affects the flow of charge in a circuit.

what is the fringe field of the capacitor. I was reading a book Electric and Magnetic Interactions by Ruth Chabay and Bruce Sherwood and they say fringe field of capacitor cancels the field due to battery and surface charges in a single cap. and battery circuit. I can scan the page from the book if you want to see.

thanks

1. What is capacitance in series?

Capacitance in series refers to the arrangement of multiple capacitors in a circuit where they are connected one after the other. This results in a single equivalent capacitance that is less than the individual capacitances.

2. How do you calculate the total capacitance in a series circuit?

The total capacitance in a series circuit can be calculated by taking the reciprocal of the sum of the reciprocals of each individual capacitance. In other words, 1/Ctotal = 1/C1 + 1/C2 + 1/C3 + ...

3. What is the effect of adding capacitors in series?

Adding capacitors in series increases the total equivalent capacitance while decreasing the overall capacitance of each individual capacitor. This means that the total energy stored in the circuit also increases, but the voltage across each capacitor decreases.

4. Can you have an infinite number of capacitors in series?

No, there is a practical limit to the number of capacitors that can be connected in series. As the number of capacitors increases, the equivalent capacitance approaches a maximum value and the circuit becomes increasingly complex and difficult to manage.

5. How does capacitance in series affect the overall impedance of a circuit?

The overall impedance of a circuit with capacitors in series is determined by the total equivalent capacitance. As the total capacitance increases, the overall impedance decreases, making the circuit more conductive to AC current.
