How do I connect capacitors in parallel?

An electronic device that holds electric charges is known as a capacitor. Capacitors can be connected in both series and parallel configurations.

When capacitors are connected in series with a voltage source, the voltage across each element is equal to the voltage across the source capacitor i.e. V1 = V2 = V3 = V4 = V5 =V

The charge stored in a capacitor is calculated using the formula Q = V x C

Capacitors in parallel Q = Q1 + Q2 +... is the total charge of capacitors.

V x C = V x C1 + V x C2 + V x C3……...

The Total Parallel capacitance is C = C1 + C2 +.......

Properties of a Capacitor

  • A capacitor is a device that resists voltage changes.
  • A capacitor's current leads the voltage by 90 degrees, which means the current is 90 degrees ahead of the voltage across the capacitor.
  • A capacitor is a perfect electrical element, so it does not absorb or dissipate energy.

Uses of a Capacitor

A capacitor's ability to store electrical energy in the form of voltage, as well as its ability to produce leading current, makes it valuable in a variety of electrical applications.

  • A tiny capacitor is connected at the end of the generator circuit during electricity generation to provide a leading power factor, which is good for reducing power losses and providing a better current waveform.
  • Capacitors are utilised in filter circuits in the transmission and reception of radio signals.
  • Capacitors are crucial components in timer and oscillatory circuits.
  • Capacitors are an excellent option for energy storage. For example, Car audio systems contain large integrated capacitors to provide essential sound amplification.
  • Capacitors can be employed as mechanical sensors because of two key features of their construction: the spacing between parallel plates and the dielectric used.

How to Calculate Parallel Capacitance in a Circuit?

To calculate the total capacitance of parallel capacitors, follow the easy instructions below. As such, they are

  • Calculate the capacitance of the circuit's parallel capacitors.
  • To calculate the resulting capacitance, add the capacitances of all parallel capacitors.

Capacitors in Parallel Examples

Question 1: If 14 F, 12 F, 42 F, 36 F, and 75 F capacitors are linked in parallel, what is their capacitance?


Given: C1 = 13F, C2 = 15F, C3 = 40F, C4 = 35F, C5 = 72F Total capacitance C = C₁ + C₂ + C3 + C4 + C5 C = 13 + 15 + 40 + 35 + 72 = 175 Hence, the total capacitance is 175 F.

FAQs on Parallel Capacitance

1. Why are capacitors connected in parallel?

Capacitors are electronic devices that store electrical energy as a charge. Because the equivalent capacitance of all capacitors involved is the sum of their individual capacitances, connecting numerous capacitors in parallel allows the circuit to store more energy.

2. When two charged capacitors are linked in parallel, what happens?

When two charged capacitors are connected in parallel, nothing will change after you connect them (no charge will flow). Because the capacitance of each capacitor remains constant, the voltages remain constant. The system will remain unchanged. Nothing seems to be moving.

3. Is it possible to use a 16V capacitor instead of a 25V one?

The voltage rating indicates the maximum voltage you can handle. Make sure you understand what you're up against. Never exceed 25V when using a 25V rated cap. For a 16v rated cap, do not exceed 16 volts.

4. What are some of the devices that make use of capacitors?

Capacitors are used in a broad variety of electronic systems, including smartphones, home appliances, electric vehicles, and medical devices.
