To avoid that the plates touch each other.
The better the dielectric, the closer the plates can be, thus making the electrostatic field on the opposite plates more intense, which allows for more electrons displaced via the charging circuit to the positive plate and more incomplete atoms (positive charges) left on the negative plate.
Remember: Being the dielectric an isolator, there is NEVER current through the capacitor.

∙ 14y agoBecause of the fundamental design of capacitors. If you look up capacitors in wikipedia or similar literature, you'll find that the size of the capacitor (measured in Farads) is dependent on the area of the plates (basically a capacitor is two plates separated by some dielectric material; electrons build up on one plate, which induces electrons to move away from the other plate). By putting two capacitors in parallel, you have effectively increased the area of the plates.
Putting capacitors in series has the opposite effect, then (decreases capacitance).

∙ 14y agoCapacitors are essentially two metal plates separated by a small distance (usually some dielectric materla is inserted between the plates). Electrons build up on one plate due to applied voltage, and this induces electrons to move away from the other plate. The total charge that can build up on a plate, then, is directly proportional to the size of the plate (physical area of the plate).
By putting capacitors in parallel, you are effectively increasing the physical area of the plates.

If the spacing between the plates doesn't change, then
the capacitance is proportional to the area of the plates.

A circuit contains a 10 pF capacitor and a 50 pF capacitor connected in parallel.What is the total capacitance of this circuit?
When capacitors are connected in parallel, the total capacitance in the circuit in which they are connected is the sum of both capacitances. Capacitors in parallel add like resistors in series, while capacitors in series add like resistors in parallel.
A 10 uF and a 30uF are placed in parallel. What is the resulting capacitance?
Total parallel capacitance is the sum of the value of the parallel capacitors. It uses the formula - Total Capacitance = C1 + C2 + C3. Hopefully, you can do the math at this point.

What are the methods to find capacitance of a capacitor?
You could measure it with a Capacitance meter. Or you could use the formula:In a parallel plate capacitor, capacitance is directly proportional to the surface area of the conductor plates and inversely proportional to the separation distance between the plates. If the charges on the plates are +q and −q, and V gives the voltage between the plates, then the capacitance C is given byFor further info on the total value of capacitance in series or parallel, Google it.
