Capacitance FAQs:


Q: Is capacitance the ability of a body to store an electric charge?

A: Yes.

Q: Is capacitance usually a shorthand for the mutual capacitance between two adjacent conductors?

A: Yes, such as the two plates of a capacitor.

Q: Is capacitance a function of frequency?

A: Yes.

Q: Is capacitance called elastance?

A: Yes.

Q: Is capacitance small unless the conductors are close together for long distances or over a large area?

A: Yes.

Q: Is capacitance a function only of the geometry of the design and the permittivity of the dielectric material between the plates of the capacitor?

A: Yes.

Q: Is capacitance very nearly proportional to the surface area of the conductor plates and inversely proportional to the separation distance between the plates?

A: Yes.

Q: Is capacitance proportional to the area of overlap and inversely proportional to the separation between conducting sheets?

A: Yes.

Q: Is capacitance the farad?

A: Yes, and named after the English physicist Michael Faraday.

Q: Is capacitance an important consideration at high frequencies?

A: Yes.

Q: Is capacitance called parasitic or "stray capacitance"?

A: Yes, Stray capacitance can allow signals to leak between otherwise isolated circuits , and it can be a limiting factor for proper functioning of circuits at high frequency.
