Current Electricity

A capacitor is a component that, like a small rechargeable battery, can retain energy in the shape of an electrical charge that produces a potential difference across its plates. Capacitors come in various sizes and shapes, varying from tiny capacitor beads used in resonance circuits to enormous power converter capacitors. However, they all have a […]

Wheatstone bridges are electrical circuits used to measure unknown electrical resistance by balancing their two legs, where one of the legs includes a novel component. Sir Charles Wheatstone improved and simplified this instrument in 1843 after it was constructed by Samuel Hunter Christie in 1833. In today’s world, digital multimeters provide the easiest way to

What Is a Metre Bridge? A metre bridge is a device that functions on the Wheatstone bridge idea. It is used to determine the unknown resistance of a substance, usually a conductor. In order to understand how a metre bridge functions, it is essential to first go through the basic concept of electric flow and

Most of us have seen dramatisations of medical help using a defibrillator to pass an electrical current through a patient’s heart to get it to beat normally. Often realistic in detail, the person applying the shock directs another person to “make it 400 Joules this time.” The energy delivered by the defibrillator is stored in

What is a Metre Bridge? A metre bridge is a device used to determine the unknown resistance of a coil or any other material that is a conductor. A metre bridge works on the same principle as a Wheatstone bridge, which is used to measure the unknown resistance in a circuit. A metre bridge is

The time was 1845, and it was the era of research and experiments when the German physicist Gustav Kirchhoff laid down two basic principles that became vital in electrical engineering and circuit analysis. These two laws mainly deal with the conservation of energy and conservation of current through the circuit and help in analysing complex

A circuit diagram (also known as a wiring diagram, electrical diagram, elementary diagram, or electronic design) is a diagram that shows how an electrical circuit works. A graphical circuit diagram employs basic depictions of parts, whereas a schematic diagram uses specified symbolic representations to show the circuit’s components and relationships. Circuit A circuit is basically

The rectifier circuit converts AC (Alternating Current) to DC (Direct Current). Half-wave, full-wave, and bridge rectifiers are the three most common types of rectifiers. All of these rectifiers have the same fundamental purpose of current conversion, however they do not transfer current from AC to DC efficiently. The full wave rectifier with centre tap as
