Electric Power

Definition: The rate at which the work is being done in an electrical circuit is called an electric power. In other words, the electric power is defined as the rate of the transferred of energy. The electric power is produced by the generator and can also be supplied by the electrical batteries. It gives a …

Difference Between MCB & MCCB

One of the major difference between the MCB (Miniature circuit breaker) and MCCB (Moulded case circuit breaker) is that the interrupt rating of the MCB is up to 1800 amps whereas the interrupt rating of the MCCB is between 10k – 200k amps. The other differences between them are explained below in details. Content: MCB …

Valve Type Lightning Arrester

Definition: The lightning arrester which consists the single or multi-gaps connected in series with the current controlling element, such type of arrester is known as the lightning arrester. The gap between the electrodes intercepts the flow of current through the arrester except when the voltage across the gap raises beyond the critical gap flashover. The …

Electric Field

Definition: The region around the electric charge in which the stress or electric force act is called an electric field or electrostatic field. If the magnitude of charge is large, then it may create a huge stress around the region. The electric field is represented by the symbol E. The SI unit of the electric …

Relay

Definition: The relay is the device that open or closes the contacts to cause the operation of the other electric control. It detects the intolerable or undesirable condition with an assigned area and gives the commands to the circuit breaker to disconnect the affected area. Thus protects the system from damage. Working Principle of Relay …

Law of Conservation of Energy

Definition: The law of conservation of energy states that the energy can neither be generated nor destroyed. It is converted from one form to another. The total input power is equal to the sum of the following three components; they are the dissipated energy, stored energy and useful output energy.The devices which convert the mechanical …

AC Motor

Definition: The motor that converts the alternating current into mechanical power by using an electromagnetic induction phenomenon is called an AC motor. This motor is driven by an alternating current. The stator and the rotor are the two most important parts of the AC motors. The stator is the stationary part of the motor, and …

Lap & Wave Winding

The armature winding is the most important part of the rotating machine. It is the place where energy conversion takes place, i.e., the mechanical energy is converted into electrical energy, and the electrical energy is converted into mechanical energy. The armature winding is mainly classified into types, i.e., the lap winding and the wave winding. …
