A dynamo is one of the major applications of electromagnetic induction. It converts mechanical energy into direct current (DC) electrical energy. It is a traditional electricity generator that generates energy on a huge scale. It played a huge role in … Read more
Electromagnetic induction is the foundation of electromagnetism. Most important discoveries of physics and electrical engineering are on the basis of this phenomenon. It is the process of producing an electromotive force (EMF) and hence current in a conductor by changing … Read more
After the successful discovery of the relationship between electric current and magnetic field, there comes its important application called the motor effect. The mechanism of producing a mechanical motion by the interaction of electrical energy and magnetism is seen in … Read more
The concept of electromagnetism lies on those imaginary lines of magnetic field. Thus, the total number of field lines entering and leaving a particular surface area is known as magnetic flux. The field lines also indicate the magnetic field strength. … Read more
The electric current along a conductor is eligible to produce a magnetic field around it. This effect is known as the magnetic effects of electric current. This is a naturally occurring fundamental phenomena which is the principle of electromagnetism. Thus, … Read more
Alternating Current and Direct Current are the configurations to provide direction to the current flow. Alternating Current (AC) vs. Direct Current (DC) comparison shows a huge difference between the two ways of current flow. DC is taken as the setup … Read more
In electricity, current can be made to flow in two ways: either uniformly or periodically back and forth. Direct current (DC) is a type of electric current where the electric charges always move in a uniform direction, thus producing steady … Read more
We know in DC circuits, the current is made to flow in a uniform direction. However, electric charge can also flow periodically in reverse direction. This flow of current is known as Alternating Current; The polarity of AC keeps changing … Read more
Definition of Near Point (Least Distance of Distinct Vision) Human beings or any other living organisms have their unique vision characteristics. A human eye can only see an object sharply and clearly to a certain extent without creating any strain … Read more
