Question

Capacitance depends on which parameters?

• A. Charge on capacitor
• B. Potential difference across capacitor
• C. Dielectric constant of the substance
• D. Area of plates
• E. Option c and d

Answer 1

The correct option is E

Option c and d

The explanation for the correct option:

Option E:

1. The ratio of a substance's permittivity to the permittivity of empty space is known as the dielectric constant.
2. It is the electrical counterpart of relative magnetic permeability and expresses the amount to which a material concentrates electric flux.
3. The larger the surface area, A, of the two conducting plates that make up the capacitor, the higher the capacitance.
4. The lower the d between the two plates, the larger the capacitance.
5. Capacitance is given by, $\mathrm{q}=\mathrm{CV}$

The explanation for incorrect options:

Option A: A charge is not stored in capacitors.

Option B: There is a potential difference when a capacitor is completely charged.

Therefore, option E is correct.
