Factors Affecting Capacitance
A parallel-plate capacitor has plates of area A, a separation distance d, and a dielectric material of permittivity ε. The capacitor is modified so that the plate area becomes 2A, the separation distance becomes d/2, and the dielectric’s permittivity becomes 2ε. By what factor is the capacitance multiplied?
