Electrical Engineering

Electromagnetic Induction : Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field.

Principle of Transformer : Electromagnetic Induction and Mutual Induction.

What is a Transformer? A transformer is a device used in the power transmission of electric energy. The transmission current is AC. It is commonly used to increase or decrease the supply voltage without a change in the frequency of AC between circuits. 

Define the Ideal Transformer? An ideal transformer is a fantasy transformer in which no losses happen at all. In another language, the transformer Input authority is equivalent to the output authority of the transformer, i.e. they have 100% competence. It is just a hypothetical transformer because there must be some losses in a genuine transformer. Transformer input Power = Transformer Output Power.

What do you mean by electric traction? Electric traction means with the electric power for the grip system. Electric traction means utilize of the electricity for railways, trams, trolleys etc. Nowadays, magnetic toehold is also used for projectile trains. And essentially dc motors are used for electric traction systems.

What do you understand by the word electrical engineering? Electrical Engineering is the grassland of Engineering that usually deals with the learning and application of electronics, electricity, and electromagnetism. It deals with elevated voltage, particularly AC above the series of 110 or 220V.

ohm's law : States that the voltage across a resistor is directly proportional to the current flowing through the resistance.

RHEOSTAT : A resistor used for regulating a current by means of variable resistance; rheostats allow only one current path.

Non-Conventional Power Plants The non-conventional sources of energy are being continuously produced in nature and are not exhaustible. Examples include wood, geothermal energy, wind energy, tidal energy, nuclear fusion, biomass, solar energy etc. The following are the power plants from non-conventional sources of energy. Thermoelectric Generator Thermionic generator Fuel-cells Power Plants Photovoltaic solar cells Power System MHD Power Plants Fussion Reactor NPP Power System Biogas, Biomass Energy Power system Geothermal Energy Wind Energy Power System Ocean Thermal energy conversion (OTEC) Wave and Tidal Wave Energy Plantation Scheme

Conventional Power Plants They include the generation of electricity from conventional sources of energy. These resources are finite and exhaustible. Once consumed, these sources cannot be replaced by others. Examples include coal, timber, petroleum, lignite, natural gas, fossil fuels, nuclear fuels etc. The conventional power plants include the following power plants, Steam Engines Power Plants Steam Turbine Power Plants Diesel Power Plants Gas Turbine Power Plants Hydro Electric Power Plants Nuclear Power Plants

Types of Power Plants There are several different types of power plants used across the world today. Power plants are classified into different groups based on the criteria used for the classification. The criteria used in this article is what source of energy is utilized to produce the electricity. Using the criteria of source of energy for electricity production, we can broadly classify power plants to, Conventional Power Plants Non-Conventional Power Plants Conventional power plants use conventional sources of energy while non-conventional power plants utilize non-conventional sources of energy.

What is the difference between MCB & MCCB, Where it can be used? MCB is miniature circuit breaker which is thermal operated and use for short circuit protection in small current rating circuit. MCCB moulded case circuit breaker and is thermal operated for over load current and magnetic operation for instant trip in short circuit condition.under voltage and under frequency may be inbuilt. Normally it is used where normal current is more than 100A.

The first power plant owned by Thomas Edison opened in New York City in 1882.

Lightning is a discharge of electricity in the atmosphere. Lightning bolts can travel at around 210,000 kph (130,000 mph), while reaching nearly 30,000 °C (54,000 °F) in temperature.

An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It is involved in powering the electrical appliances you use every day: computers, smartphones, washing machines, flashlights and any other common electric device.

Static electricity usually happens when you rub things together. It’s why a balloon will stick to you after rubbing it against your clothes. Or why you get a shock when walking across carpet and touching something metallic. It’s also the cause of lightning. As rain clouds move through the sky, they rub against the air around them.

Electricity is a type of energy that builds up in one place, or flows from one place to another. When electricity gathers in one place it is known as static electricity. Electricity that moves from one place to another is called electric current.

Water doesn’t actually conduct electricity. Impurities in water is what makes it conduct electricity.
