Capacitor Charge Calculator

Formula

The formula to calculate the charge stored in a capacitor (Q) is:

\[ Q = C \cdot V \]

Where:

\(Q\) is the charge stored in the capacitor (coulombs)
\(C\) is the capacitance of the capacitor (farads)
\(V\) is the voltage across the capacitor (volts)

Capacitor Charge Definition

Capacitor charge is the amount of electrical energy stored in an electric field within a capacitor. This charge is a result of the separation of charges within the capacitor when a voltage is applied across its terminals. The ability of a capacitor to store charge is measured by its capacitance, which is the ratio of the charge stored to the voltage across the capacitor.

Example Calculation

Let's assume the following values:

Capacitance (C) = 0.01 F
Voltage (V) = 12 V

Using the formula to calculate the charge (Q):

\[ Q = 0.01 \cdot 12 = 0.12 \]

The charge (Q) is 0.12 coulombs.
