pls follow me
Explanation:
Doubling the distance between capacitor plates will reduce the capacitance two fold. Doubling the distance between capacitor plates will increase the capacitance two times. Doubling the distance between capacitor plates will increase the capacitance four times.Capacitance is directly proportional to the electrostatic force field between the plates. This field is stronger when the plates are closer together. Therefore, as the distance between the plates decreases, capacitance increases. ... Therefore, as the dielectric constant increases, capacitance increases
