Question

Quizplus · Accepted Answer

The electrical analog of a spring constant is capacitance (C), not inductance (L) or resistance (R). The reason for this is that a capacitor stores energy in an electric field, just as a spring stores energy in its mechanical deformation. The formula for electrical capacitance is C = Q/V, where Q is electric charge and V is voltage. The units of capacitance are coulombs per volt, which can also be written as farads (F). The larger the capacitance, the more charge can be stored for a given voltage, just as the larger the spring constant, the more force is needed to stretch or compress the spring. Therefore, the electrical analog of a spring constant is the inverse of capacitance, which is 1/C.
