Electrostatic Potential and Capacitance

Question:

Case: Read the passage and answer the following question(s).

A capacitor is a system of two conductors separated by an insulator. The electric field in the region between the conductors is proportional to the charge Q. That is, if the charge on the capacitor is, say doubled, the electric field will also be doubled at every point. A parallel plate capacitor consists of two large plane parallel conducting plates separated by a small distance. Dielectrics are introduced between the plates to change the nature of capacitors. Capacitors can be connected in series and parallel in a circuit.Capacitance

What is the effective capacitance when two capacitors are connected parallel?

Options:

C = C1+C2

1/C = C1+C2

1/C = 1/C1+1/C2

None of the above

Correct Answer:

C = C1+C2

Explanation:

To calculate the total overall capacitance of a number of capacitors connected in this way you add up the individual capacitances using the following formula: C = C1+C2
