## Reluctance

What is Reluctance? Magnetic reluctance is defined as the opposition offered by a magnetic circuit to the production of magnetic flux. Magnetic reluctance is the property of the material that opposes the creation of magnetic flux in a magnetic circuit. Magnetic reluctance also known as reluctance, magnetic resistance, or a magnetic insulator. In an electrical …

## Permeance

What is Permeance? Permeance is a measure of the ease with which a magnetic flow is applied using an object or a magnetic circuit. Permeance is the reciprocal of reluctance. Permeance is directly proportional to the magnetic flux and is denoted by the letter P. From the above equation we can say that the quantity …

## How To Measure Current

In an electrical and electronic circuit, current measurement is an essential parameter that needs to be measure. An instrument can measure the electric current called an ammeter. To measure current ammeter must connect in series with the circuit whose current is to be measured. The measurement of current through the resistor by using an ammeter …

## Conventional Current vs Electron Flow

Now we understand conventional current flow and electron flow. The particles that carry the electric charge through the conductors are either moving or free electrons. The direction of the electric field within the circuit, by definition, the rule that good test charges are pushed. Thus, these negative charge particles, i.e., electrons, flow opposite the electric …

## AC vs DC current

Based on the flow of charge, the electric current is classified into two types, i.e. alternating current (AC) and direct current (DC) AC Current The flow of electric charge in a periodically reverse direction is known as alternating current (AC). AC is also referred to as “AC Current”. Although this is technically saying the same …

## What is Electric Current?

Electric Current An electric current is defined as a stream of charged particles such as electrons or ions that run through an electric conductor or space. Flow charge rate using a conducting medium with respect to time. Electricity is expressed mathematically (eg in formulas) using the symbol “I” or “i”. The current unit says ampere …

## Electrical switches and types

Electrical switching with mechanical or relay contacts. These types of switches can control a wide range of current options and voltage. Electrical switches can adapt to misunderstandings in the application / application to ensure no leakage current and make them available in multiple circuits, actuators, and housing styles. Disadvantages include their number, limited communication life …

## What is NO and NC Switch Contacts in electrical?

Normally-open and Normally-closed Switch Contacts Electrical switch contacts are either normally-open or normally-closed, depending upon the open or closed status of the contacts under “normal” conditions. But what exactly defines “normal” for a switch? The answer is not complicated, but it is often misunderstood because of the ambiguous nature of the common word. The “normal” state …

## What is capacitance? How to measure.

The property of the capacitor is called as capacitance. The ability of a capacitor to store energy is measured by capacitance. It is defined as the ratio between the charge stored Q by a capacitor to the voltage V across the terminal. The capacitance is denoted as “C”. Capacitance can be mathematically expressed by Also, …

## What is capacitor? Working principle of it.

Capacitor Capacitor stores electric charge. It is looks like battery it stores energy in a different way. It is stores much energy in battery. It releases charge very faster. Capacitor is very useful that’s why it is used in all circuit boards. It is one of the fundamental passive components. It is separately or jointly …
