Capasitor Components That Can Store Electrical Charge and Energy

Posted on

Explanation of Capacitors – Capacitors are one of the electronic components that can store electric charges. If you don’t understand what an electric charge is, please read the Explanation of Electricity. Capacitors is passive components, meaning that to work there is no need for energy from other components. The capasitor symbol is shown as shown below. In image (a) are symbols for non-polarizing capacitors and images (b) for capacitors that have polarization voltage (+ and -)

Generally capacitors are made of two sheets of conductor separated by an insulating material. Insulation materials (insulators) are materials that cannot conduct electricity. Example;

  • Air
  • Glass
  • Fiber
  • Mica
  • Ceramics

This insulation material on the capacitor is also called a dielectric material.


Capasitor Function

In electronic circuits, capacitors have the main functions, that is:

  • Filter or Filter on the Power Supply
  • Connect the Power line or Power Line Decoupling
  • Hold the DC Voltage and Skip the AC Voltage
  • Electric Energy Storage
  • Signal filter


Type of the Capasitor

Based on the dielectric material, the capacitor is divided into:

  • Electrolytic Capacitors
  • Ceramic Capacitors
  • Film Plastic Capacitors
  • Variable Capacitors
  • Tantalum Capacitors
  • Mika Capacitors


Capacitor working principle

When the capacitor is connected to a DC voltage source, the DC electric charge will flow in and be stored in the capacitor. The ratio of the amount of electric charge that can be stored in the capacitor is called capacitance. Capacitors can store electrical charges for a long time after the DC voltage is released from the capacitor’s. Please be careful, it can be electrocuted, the higher the capacitance value, the higher the stun power.

This capacitance is measured by farad (taken from the name of its inventor, Michael Faraday), which is where 1 Farad Capacity is interpreted when a capacitor can store a current of 1A at a voltage of 1V. 1 Ampere is 1 Coloumb per second. Reread the Explanation of Electric Current to understand what is called couloumb. 1 Farad = 1 Coulomb / 1 Volt.

Capasitor Formula

Following is the basic formula for calculating this capacitance:

C = Q / V or C (capacitance) = Q (electric charge) divided by V (voltage)


Q = V x C or Q (electric charge) = V (voltage) multiplied by C (capacitance)


V = Q / C or V (voltage) = Q (electric charge) divided by C (capacitance)

C = Capacitance (F)
Q = Coulomb (C)
V = Voltage (V)


Capacitor Unit

Basically the unit of capacitance is Farad “F”, but in electronic components it is very rare to find capacitors that have a value of 1 Farad, however piko Farad, nano Farad, micro Farad and miliFarad. Please see the following for a comparison of values.

1 F = 1,000 mF
1 F = 1,000,000 uF
1 F = 1,000,000,000 nF
1 F = 1,000,000,000,000 pF

  1. Hello would you mind sharing which blog platform you?re working with?
    I?m planning to start my own blog soon but I?m having a tough time making
    a decision between BlogEngine/Wordpress/B2evolution and Drupal.

    The reason I ask is because your design and style seems different then most blogs and I?m looking for something completely unique.

    P.S My apologies for getting off-topic but I had to ask! https://www.m2move.ca
