Definition of Capacitance
Definition of Capacitance
Capacitance (C) is the ability to store charge per voltage, defined as C = Q/V.
Capacitance Formula
Capacitance Formula
The formula to find capacitance is C = Q/V, where Q is charge and V is potential difference.
Effect of Q on C
Effect of Q on C
Increasing or decreasing charge (Q) does not affect capacitance (C); C remains constant.
