The Easiest Way to Understand Ohm’s Law

Ohm’s law describes the amount of resistance the current has to face while it travels between two points. Definition: Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points, given that the physical conditions such as length of wire, temperature etc remain constant. What’s actually […]

What is Air Circuit Breaker? Explain two types?

Air Circuit Breaker (ACB) is an electrical device used to provide Overcurrent and short-circuit protection for electric circuits over 800 Amps to 10K Amps. These are usually used in low voltage applications below 450V. there are two types of air circuit breakers 1.Air-Break Circuit Breakers In Air-Break Circuit breaker the contact separation and arc extinction occur in […]

Power Transformer vs Distribution Transformer | Electrical Darwaza

power vs distribution transformer

Power transformers are used for transmission & receiving purpose, whereas distribution transformers are used only for distribution purpose. Power transformer voltage ratio varies b/w 756 kV to 11kV. Whereas the distribution transformer voltage ratio varies b/w 33kV to 430V. Power transformers usually have higher MVA rating compare to distribution transformers.

Lightning Arresters Types | Electrical Darwaza

Types of Lightning Arresters

The lightning arrester protects the electrical equipment from lightning. It is placed very near to the equipment and when the lightning occurs the arrester diverts the high voltage wave of lightning to the ground. The selection of arrester depends on the various factors like voltage, current, reliability, etc. The lightning arrestor is mainly classified into […]

Difference Between Pump and Motor | Electrical Engineering

motor vs pump

The motor is an electromechanical device, which consists of rotating conductors and magnetic field to transform electrical energy into mechanical torque. Whereas pump is a hydro-mechanical device that converts mechanical torque into hydraulic/pressure energy. Motoring action ( electric one ) obtained based on Faraday’s law of electromagnetic induction and motor law. Whereas pumping action achieved […]

Different Types Of Transformer | Electrical Darwaza

transformer types

A transformer is a device working on mutual inductance principle to convert electrical energy from one voltage/ current level to another. There are different types of transformers used for different purposes. (1) POWER TRANSFORMER Laminated core Transformer Toroidal Transformer Auto transformer Variable auto transformer Induction regulator Transformer(high voltage transformer) Polyphase transformer Grounding transformer Phase-shifting transformer Variable-frequency […]

Difference between a Contactor and a Relay | Electrical Darwaza

contactor vs relay

A contractor is an electromagnetic device which is used to make or break of an electrical circuit. there is two type of contractor. power contactor. auxiliary contactor. Power contactor is used in power circuit like switch on/off of a motor capacitor. while auxiliary contactor is used to switch on or off of a control circuit. a power contactor have 3 main contacts while an auxiliary contactor has many contacts like 1no+1nc 2no+2nc ect..power contactor is generally used where we required to make and break a large current carrying circuit. The Relay is similar to an auxiliary contactor which is used […]

Difference between Foundation and Footing | Civil Engineering Facts

foundation and footing

Foundations are broadly classified as : Shallow Foundations Deep Foundations According to Karl von Terzaghi, a foundation is shallow if its depth is equal to or less than its width. Foundations constructed by open excavation are also called shallow foundations. The term footing is used in conjunction with shallow foundations commonly. A footing is a foundation unit constructed in brickwork, masonry or concrete […]

6 Types of Building Materials Used In Construction | Civil Engineering Fact

The building material is any material which is used for a construction purpose. Many naturally occurring substances, such as clay, sand, wood and rocks, even twigs and leaves have been used to construct buildings.The manufacture of building materials is an established industry in many countries and the use of these materials is typically segmented into specific […]
