In summary, a capacitor is an electronic component that stores electrical energy in an electric field. It works by creating a charge imbalance between two conductive plates, which stores energy for later use. The unit of measurement for capacitance is the farad (F), but smaller units such as microfarads (µF) and nanofarads (nF) are commonly used. There are different types of capacitors, each with unique characteristics and uses in electronic circuits. Capacitors can be used for filtering, coupling, timing, and energy storage in a variety of electronic devices.

Homework Statement


Consider two identical capacitors with parallel plates (the distance between the plates is (d). In each of them a metal (thickness d/3, surface equal to the plates surface) is placed right in between the plates. In one of them a metal part is connected to the upper plate, an in the other one its not connected.

The capacity is
1) greater in the capacitor with connection
2) vice versa
3) its equal
4) we can't tell (why?)


The Attempt at a Solution



I think that its greater in the one with connection

FAQ: A simple capacitors related question

What is a capacitor?

A capacitor is an electronic component that stores electrical energy in an electric field. It consists of two conductive plates separated by an insulating material called a dielectric.

How does a capacitor work?

When a voltage is applied across a capacitor, one plate becomes positively charged and the other becomes negatively charged. This creates an electric field between the plates, which stores energy. The capacitor discharges when the voltage is removed, releasing the stored energy.

What is the unit of measurement for capacitance?

The unit of measurement for capacitance is the farad (F). However, most capacitors have much smaller capacitance values, so you will often see units such as microfarads (µF), nanofarads (nF), and picofarads (pF) used.

What are the different types of capacitors?

There are many types of capacitors, including ceramic, electrolytic, film, and tantalum capacitors. Each type has its own unique characteristics and is used for different purposes, such as filtering, decoupling, and timing circuits.

How are capacitors used in electronic circuits?

Capacitors are used in electronic circuits for a variety of purposes, including filtering, coupling, timing, and energy storage. They are commonly used in power supplies, audio circuits, and electronic filters.
