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.
