Magnetism

Magnetism: About twenty millennia ago ancient peoples discovered that certain lead colored stones posses a peculiar property of attracting fillings of small pieces of irons and other stones. Because this mineral was found in Magnesia ( a region in … [Continue reading]

How to test a Capacitor?

How to test a Capacitor?

Capacitors isĀ one of the most used electronic components in electronics and electrical circuits and devices. Many time we need to test a capacitor to make sure it is working fine and is not causing the circuit or device to malfunction. Testing a … [Continue reading]

Charging and Discharging of Capacitor

Charging and Discharging of Capacitor

A capacitor is charged when we supply a voltage with current running through the capacitor, in the process the capacitor accumulates charges and is called charged. A charged capacitor can then be discharged by draining the current through it's two … [Continue reading]

[How To] Hide the admin bar in WordPress.

WordPress automatically displays an admin bar at the top of each page when users are logged in to the website. In many cases we need to hide the admin bar, but WordPress does not allows us to disable the admin bar easily through settings. If we … [Continue reading]

Current-Voltage relationship in Capacitor

Current-Voltage relationship in Capacitor

From the definition of capacitance it is known that there exists a relationship between the charge on a capacitor and the voltage or potential difference across the capacitor which is simply given by: Where, Q = total charge in the capacitor. C … [Continue reading]

Energy Stored in a Capacitor

Energy Stored in a Capacitor

When a capacitor is charged from it's original charge less state to the fully charged state the Capacitor absorbs some energy from the source from which it is being charged, and thus the capacitor stores some amount of charge in it. The energy is … [Continue reading]

Types of Capacitors

Capacitors are one of the most used and useful electronic component used in any modern electronic and electrical circuit and devices. Capacitors have a long history or production and usage, with more than 250 years of history capacitors are one of … [Continue reading]

Capacitors in Series and Parallel

Capacitors in Series and Parallel

Capacitors are usually used in combinations of series, parallel or both in various circuits and devices. So, it is good to discuss the resultant capacitance of a series or parallel combination of capacitors. Combining capacitors in series and … [Continue reading]

Cylindrical Capacitor

Cylindrical Capacitor

A capacitor made up of two concentric cylindrical shell or wires separated to each other by a dielectric in between them as shown in the figure below is known as the Cylindrical Capacitor. Capacitance of Cylindrical Capacitor: Let, The … [Continue reading]

Parallel Plate Capacitor

Parallel Plate Capacitor

A parallel plate capacitor is a simple arrangement of electrodes and dielectric to form a capacitor where two parallel conductive plates are used as electrodes with a medium or dielectric in between them as shown in the figure below: Capacitance … [Continue reading]
