By planning and practicing your answers, you can boost your confidence and increase your chances of getting the outcome you want. In this post we cover all electrical engineering topic and contain topic wise MCQ objective type questions. Don't refresh. Just take a look.
What is electricity? Ans : Electricity is a general term used for all phenomena caused by electric charge whether static or in motion. Ans : There are two types, 1 static Electricity and 2 Current Electricity. Ans : Static electricity means electricity at rest in contradistinction to dynamic or current electricity the effects of which are purely due to the electrostatic field produced by the charge. As it is obtained by rubbing two substance such as glass and silk it is also called frictional electricity. Ans : Current electricity means the electricity in motion the effects of which are due to the flow of electrons in a conductor.
Pu stands for per unit and this will be used in single line diagram of power distribution and it is like a huge electrical circuit with no of components generators, transformers, loads with different ratings in MVA and KV. Those values are called as pu values. Operation carried out in Thermal power stations? The water is obtained in the boiler and the coal is burnt so that steam is obtained this steam is allowed to hit the turbine , the turbine which is coupled with the generator generates the electricity. Why link is provided in neutral of an ac circuit and fuse in phase of ac circuit?
Both generator and alternator work on the same principle they convert mechanical energy into electrical energy. An RLC circuit carries an electrical circuit consisting of a resistor R and inductor L and a capacitor C , connected in parallel or series. This circuit is called a second order circuit as any voltage or current in the circuit can be described by a second order differential equation. Wire is sized by American Wire Gauge system.

In today post, we will be sharing the frequently asked electrical engineering interview questions and answers related to electrical engineering. Electrical engineering deals with high voltage especially AC above the range of or V. When manufacturers design a transformer, they have no idea which kind of load will be connected to the transformer. The output of real power may vary depending on the power factor. A real transformer has the following losses;. The losses occur due to the current flow through the windings that causes resistive heating of the conductors. There are two types of core or iron losses.
