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.

How does a capacitor store charge?

Consider a circuit having a capacitance C and a resistance R which are joined in series with a battery of emf ε through a Morse key K, as shown in the figure. When the key is pressed, the capacitor begins to store charge. If at any time during charging, I is the current through the circuit and Q is the charge on the capacitor, then

How does an uncharged capacitor work?

In figure (a), an uncharged capacitor has been illustrated, because the same number of free electrons exists on plates A and B. When a switch is closed, as has been shown in figure (b), then the source, moves electrons towards B via the circuit. In this way, the flow of electrons starts from plate A, and electrons start to store on plate B.

What happens if a capacitor is discharged through a resistor?

If the capacitor is discharged through a resistor with a resistance of R ohms, conceptually the time for the charge to neutralize (move from one plate to the other) will depend on the value of the resistor. The charge will neutralize rapidly if the resistor has a small value and slower if the resistor is larger.

What happens when a capacitor is fully charged?

When a capacitor gets fully charged, the value of the current then becomes zero. Figure 6.47; Charging a capacitor When a charged capacitor is dissociated from the DC charge, as has been shown in figure (d), then it remains charged for a very long period of time (depending on the leakage resistance), and one feels an intense shock if touched.
