Enter the capacitance of the capacitor and the voltage across it into the calculator to determine the charge stored in the capacitor.
Capacitor Charge Formula
The following formula is used to calculate the charge stored in a capacitor.
Q = C * V
Variables:
- 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)
To calculate the charge stored in a capacitor, multiply the capacitance by the voltage across it.
What is Capacitor Charge?
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.
How to Calculate Capacitor Charge?
The following steps outline how to calculate the charge stored in a capacitor.
- First, determine the capacitance of the capacitor (C) in farads.
- Next, determine the voltage across the capacitor (V) in volts.
- Next, gather the formula from above = Q = C * V.
- Finally, calculate the charge stored in the capacitor (Q) in coulombs.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
capacitance of the capacitor (C) = 0.5 farads
voltage across the capacitor (V) = 10 volts
