How does the distance between the plates of a parallel plate capacitor affect its capacitance?

• The distance between the plates of a parallel plate capacitor has no effect on its capacitance.

• The capacitance of a parallel plate capacitor decreases as the distance between the plates increases.

• The capacitance of a parallel plate capacitor increases as the distance between the plates increases.

• The capacitance of a parallel plate capacitor remains constant regardless of the distance between the plates.

What is the formula for calculating the total resistance of resistors in series?

• R = R1 + R2 + R3 + ...

• R = 1/(1/R1 + 1/R2 + 1/R3 + ...)

• R = R1 * R2 * R3 * ...

• R = R1 - R2 - R3 - ...

What is the dielectric constant?

How does the dielectric constant affect the capacitance of a capacitor?

• The dielectric constant only affects the resistance of a capacitor, not the capacitance.
