What is electrical machinery and equipment?

Expand All. The Indian electrical equipment industry comprises of two broad segments – 1. Generation equipment (boilers, turbines, generators) Transmission & Distribution (T&D) and allied equipment like transformers, cables, transmission lines, etc.

What is the concept of electrical machine?

Electric machines are devices used for energy conversion, mostly between mechanical and electrical forms. An electric motor is a machine that converts the electrical energy given to it as input to mechanical energy output; a generator does the reverse by producing electrical energy from mechanical energy input.

What are the principles of electrical machines?

An electric generator is an electrical machine which converts mechanical energy into electrical energy. A generator works on the principle of electromagnetic induction. It states that whenever a conductor moves in a magnetic field, an emf gets induced within the conductor. This phenomenon is called as generator action.

What is the importance of electrical machines?

The energy conversion between electrical and mechanical power is performed by the electrical machine in both directions. Electrical machines can be used for different ranges of speed. It can be used as motor particularly in traction, electrical vehicles, etc. or as generators in power station, wind turbines, etc.

Is transformer a machine?

Transformers are electrical machines that change electricity from one voltage to a different voltage. Voltage is the measure of the electrical force that pushes electrons around a circuit.

What are electronic equipments?

Electronic Equipment means any electronic equipment including an electronic terminal (for example, a merchant terminal or ATM), computer, cash deposit machine, television, fax machine, telephone and mobile telephone.

What is used in electrical equipment?

Electrical equipment means any apparatus, appliance, cable, conductor, fitting, insulator, material, meter or wire that is used for controlling, generating, supplying, transforming or transmitting electricity at a voltage greater than extra low voltage or is operated by electricity at a voltage greater than extra-low …

What is electrical machine and its types?

The electric machines are of three main types, transformer, generator, and motor. Electrical Transformer: In the transformer, both input and output are electrical power. Electrical Generator: In a generator, the input is mechanical power and the output is electrical power.

What is electrical equipment industry?

What are the two main types of circuit?

There are two types of circuit we can make, called series and parallel. The components in a circuit are joined by wires. If there are no branches then it’s a series circuit. If there are branches it’s a parallel circuit.

What are the 6 components of a circuit?

Some basic circuit components which are used in an electronic system is given below.
  • Cell. A cell is a device used to power electrical circuits. …
  • Switch. A switch is a device that can break an electrical circuit by diverting the current from one conductor to another conductor or an insulator. …
  • Light Bulb. …
  • Connecting Wires.

Whats the unit for current?

ampere
The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 x 10–19 when expressed in the unit C, which is equal to A s, where the second is defined in terms of ΔνCs.

What is called resistance?

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.

What is the name of circuit?

An electrical circuit is a path in which electrons from a voltage or current source flow. The point where those electrons enter an electrical circuit is called the “source” of electrons. The point where the electrons leave an electrical circuit is called the “return” or “earth ground”.

What units is voltage?

The SI unit for voltage is Volt and is represented by the letter v. volt is a derived SI unit of electromotive force or electric potential.

What is current formula?

Current is usually denoted by the symbol I. Ohm’s law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm’s law is I = V/R.

What is meant by 1 ampere?

An ampere is a unit of measure of the rate of electron flow or current in an electrical conductor. One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second.
