Capacitor Voltage Calculator
Enter the values of total charge stored, Q(C) and capacitance, C(F) to determine the value of capacitor voltage, Vc(V).
Capacitor Voltage Formula:
The voltage across a capacitor is a fundamental concept in electrical engineering and physics, relating to how capacitors store and release electrical energy.
A capacitor consists of two conductive plates separated by an insulating material or dielectric.
The voltage across a capacitor is directly related to the amount of charge it stores and its capacitance.
This formula is pivotal in designing and analyzing circuits that include capacitors, such as filtering circuits, timing circuits, and energy storage systems.
Capacitor voltage, Vc(V) in volts is calculated by dividing the value of total charge stored, Q(C) in coulombs by capacitance, C(F) in farads.
Capacitor voltage, Vc(V) = Q(C) / C(F)
Vc(V) = capacitor voltage in volts, V.
Q(C) = total charge stored in coulombs, C.
C(F) = capacitance in farads, F.
Capacitor Voltage Calculation:
- Calculate the voltage across a capacitor with a stored charge of 0.002 coulombs and a capacitance of 0.0001 farads:
Given: Q(C) = 0.002C, C(F) = 0.0001F.
Capacitor voltage, Vc(V) = Q(C) / C(F)
Vc(V) = 0.002 / 0.0001
Vc(V) = 20V.
- Determine the voltage across a capacitor that stores a charge of 0.005 coulombs and has a capacitor voltage of 100V:
Given: Q(C) = 0.005C, Vc(V) = 100V.
Capacitor voltage, Vc(V) = Q(C) / C(F)
C(F) = Q(C) / Vc(V)
C(F) = 0.005 / 100
C(F) = 0.00005F.
Applications and Considerations:
- Energy Storage Systems: Capacitors are essential for modern energy storage systems, providing quick release and storage of energy.
- Electronic Filters: Used in circuits to manage frequency response in audio, radio, and other signal-processing applications.
- Power Conditioning: Critical for smoothing voltage fluctuations and providing stable power supply in various electronic applications.
