About Us



This blog is a place for electrical and electronics engineering students providing unique and quality resources and articles. It also provide information about projects of electrical and electronics.


This blog consist a lot of interview questions which are asked in most exam.

There are following topics in this blog

  • electrical machines
  • power system
  • power electronic
  • electrical measurements
  • electronic devices
  • Emphasizes the conceptual understanding of each topic, logical approach
  • plenty of illustration the theoretical concepts

My name is Prabhat. I'm an Electrical Engineering student as well as an enthusiast blogger. I am studying in the second year of B.E. (Electrical) in Rajasthan Techanical University Rajasthan, India.


I have started this blog with an intention of helping electrical engineering students to understand the basics of electrical engineering in easy words. This blog is mostly targeted to those students from countries where English is not a native language, like India. Such students find it quite hard to understand very clearly from a reference book, just because the language used in most of the reference books is really hard to understand. Do you think that basics of electrical can be understood clearly and easily from this blog. Am I doing it good? I hope that I'm keeping my words and my posts are helping you.



I like to stay in touch with my readers. So, never hesitate to get in touch.

Transformer multiple choice questions part 1

Hello Engineer's Q.[1] A transformer transforms (a) frequency (b) voltage (c) current (d) voltage and current Ans : D Q.[2] Which of the following is not a basic element of a transformer ? (a) core (b) primary winding (c) secondary winding (d) mutual flux. Ans : D Q.[3] In an ideal transformer, (a) windings have no resistance (b) core has no losses (c) core has infinite permeability (d) all of the above. Ans : D Q.[4] The main purpose of using core in a transformer is to (a) decrease iron losses (b) prevent eddy current loss (c) eliminate magnetic hysteresis (d) decrease reluctance of the common magnetic circuit. Ans :D Q.[5] Transformer cores are laminated in order to (a) simplify its construction (b) minimize eddy current loss (c) reduce cost (d) reduce hysteresis loss. Ans : B Q.[6] A transformer having 1000 primary turns is connected to a 250-V a.c. supply. For a secondary voltage of 400 V, the number of secondary turns should be (a) 1600 (b) 250 (c) 400 (d) 1250 A...

Condition for Maximum Power Developed In Synchronous Motor

The value of δ for which the mechanical power developed is maximum can be obtained as, Note : Thus when R a is negligible, θ = 90 o for maximum power developed. The corresponding torque is called pull out torque. 1.1 The Value of Maximum Power Developed        The value of maximum power developed can be obtained by substituting θ = δ in the equation of P m .        When R a is negligible,     θ = 90 o  and cos (θ) = 0 hence, . . .               R a = Z s cosθ   and X s = Z s sinθ        Substituting   cosθ = R a /Z s in equation (6b) we get,         Solving the above quadratic in E b we get,        As E b is completely dependent on excitation, the equation (8) gives the excitation limits for a...

Effect of Slip on Rotor Parameters : Part2

Effect of Slip on Rotor Parameters 2. Effect of Slip on Magnitude of Rotor Induced E.M.F        We have seen that when rotor is standstill, s  = 1, relative speed is maximum and maximum e.m.f. gets induced in the rotor. Let this e.m.f. be,                 E 2 = Rotor induced e.m.f. per phase on standstill condition         As rotor gains speed, the relative speed between rotor and rotating magnetic field decreases and hence induced e.m.f. in rotor also decreases as it is proportional to the relative speed N s - N. Let this e.m.f. be,                E 2r = Rotor induced e.m.f. per phase in running condition  Now        E 2r α N s while E 2r α N s - N        Di...
