Under which conditions a synchronous motor will fail to pull into step? Since, we have V=q/c, hence zero charge corresponds to zero voltage. 0. When the main current in the coil decreases, the induced current opposes the decay of current in the coil. Define Ampere? What is the method to solve circuit using Source Transformation? An ideal filter will attenuate all signals with frequencies less than and greater than 100 MHz thus providing the best channel sound quality without any distortion. Could you measure Voltage in series? An ideal voltage source has zero internal resistance. Kirchhoff’s First law. 42. For example, an iron core conductor is bilateral but it is non linear. Electrical Engineering is a branch and discipline of electrical concepts and its applications related to electrical systems, electromagnetic and electronic devices. Best Electrical Circuits Interview Questions and Answers. Q.20. Could you measure current in parallel? It takes energy from a battery or some other power source to move electrons to one of the plates and away from the other. Mathematically, Question4: What is sampling? 12. Let us move to the next Digital Electronics Interview Questions. 26. F = B I L Newtons, where B in tesla, I in amps and L in meters. Categories Interview Questions, Basic Electrical, Battery, Electric Vehicles, Electrical Machines, Electronics, Substation, Transformer Nervous about an upcoming Electrical Engineer interview? What consists of cooling water circuit and coal & ash circuit in steam power plant? At what base you will tell the direction of rotation of DC Motors and Generators? At very low Temperatures, the resistance of some materials falls to zero. Basically, it uses a conductor that is wound into a coil, and when electricity flows into the coil from the left to the right, this will generate a magnetic field in the clockwise direction. V ? Q.17. The algebraic sum of all the currents entering or leaving a node in an electric circuit is equal to zero. in mesh analysis) or vice versa. Therefore, it is concluded that a linear network must be bilateral but a bilateral network is not necessarily linear. State clearly the superposition theorem. 23. 14. Question5: State sampling theorem. Several sources give Copper p = 1.7 × 10-6 ohms per cm cube and a = 0.004. How to calculate Energy stored in an inductance? also we can provide Electrical objective questions books & Interview questions. It is particularly advantageous where a single resistor or load in a circuit is subject to change. The circuit breaker does not require a replacement like the fuse which needs to be replaced. Before the signal is transmitted, it is converted into digital form. The term cos f is called the power factor and is an important parameter in determining the amount of actual power dissipated in the load. Answer: The time rate of flow of electric charge across a cross-sectional boundary is termed as current. It can also be subdivided into ideal and non-ideal categories. Frequently asked interview questions with answers under the subjects like electrical machines,Transmission and distribution,Power electronics and some general basic questions. A load can either be of resistive, inductive or capacitive nature or a blend of them. Superposition theorem can be formally stated as follows: A capacitor (originally known as a condenser) is a passive two-terminal electrical component used to store energy electrostatically in an electric field. Answer: The property of coil due to which it opposes any increase or decrease of current or flux through it is called self-inductance. It is the most fundamental law used in circuit analysis. Statement. Most Asked Technical Basic CIVIL | Mechanical | CSE | EEE | ECE | IT | Chemical | Medical MBBS Jobs Online Quiz Tests for Freshers Experienced. The usual way is to plot the amplitude in dB and phase in degrees or radians versus the logarithm of frequency. The above mentioned are few electrical interview questions and answers. The resultant is given by the algebraic sum of all currents or voltages caused by each source acting independently. 3. Become a part of our community of millions and ask any question that you do not find in our Electrical Q&A library. There are many ways to go into technical based question but that depends on what sort of industry or work field you are going to work. What is the difference between Voltages or Potential Difference? In an electric circuit, it is often convenient to have a voltage source rather than a current source (e.g. 20. Powerbuilder Interview Questions ; Question 18. For a capacitive type load I leads V, hence Leading power factor 41. Clearly RN = RTH. Thus inductor acts as open circuit for the new applied source at the instant of switching. What is the function of the capacitor? Circuit Breaker Interview Questions & Answers What is a Circuit Breaker? When the main current in the coil decreases, induced current developed in the neighboring coil opposes the decay of current in the coil. Differentiate between Magnetic field and Magnetic Flux? Answer: Mutual-inductance is the property of two coil because of which each opposes any change in the current flowing through the other by developing an induced emf. Voltage regulation (VR) is an important measure of the quality of a source. 17. Elaborate Thevenin’s Theorem? It is important to highlight that in AC circuits, the product of voltage and current yields the apparent power which is measured in volt-amperes or VA. KW which is also written ad Kilo-Watt is the real power that is actually converted to the useful work. Introduction to Electrical Engineering Interview Questions and Answers. Answer: A network in which physically separate resistors, capacitors and inductors can be represented. What does the term Power Factor shows? Answer: The current through an inductor cannot change instantaneously. Phasors simplify this analysis by considering only the amplitude and phase components of the sine wave. Q.24. Network must be time invariant. No, Current is always measured through (in series with) a circuit element. 13. Current Electricity 2. equivalent to a short circuit. By Vani Raj-October 11, 2018. No field excitation; Excessive load; Excessive load inertia; Do stepper motors have internal or external fans? At what factor Resistance R of a conductor depends? Differentiate between ideal and non-ideal voltage sources? Experimental results for a coil of length S meters, diameter d meters and radial thickness t meters with at core indicate L = 3 d2 N2 / (1.2 d + 3.5 S + 4 t) micro Henneries. Twitter. Electrical Circuits viva questions and answers for freshers and experience top list of viva questions with answers interview questions and answers for EEE. An inductor can take many forms. 48. What do you mean by Phasors? A purely reactive load where f ? 10. 39. KVAR is also termed as Kilo-Volt Reactive this power is used for magnetic field excitation and flows back and forth between source and load. In other words, it can be said that the load resistance must match the Thevenin’s resistance for maximum power transfer to take place i.e., (Rs = RTH) = RL The total current leaving a point on an electrical circuit = total current entering In such cases, the theorem considers each source separately to evaluate the current through or voltage across a component.
