Question

Two capacitors are wired in parallel in a circuit. Which of the following will affect the overall capacitance of the capacitors?
I. The voltage
II. The current
III. The physical shape and size of the capacitors

• A. I only
• B. I and II only
• C. III only
• D. I, II, and III

Answer 1

Answer: (C)

III only

The capacitance of a capacitor is given by $\frac{A{ϵ}_0}{d}$

where $A$ is the area of the plates

$d$ is the distance between the plates.

Hence the capacitance depends upon the physical shape and size of the capacitors.

Correct answer is option C.
