The color code may differ around the world but usually, the earth wire remains the same i.e green with yellow stripes. Start Your Free Software Development Course, Web development, programming languages, Software testing & others. For a DC supply, there will be no inductance & there will be no mutual induction between the windings. A Resistor is an electrical component where it also opposes the flow of current and is a two-terminal component. Answers Pdf Free Download. There are two reasons for increasing the current; 1) Either the total resistance of the circuit is reduced by half. In gases the flow of current is due to, D. Electrons, positive ions and negative ions, 2. A Circuit Breaker is a protective electromechanical device used to control the flow of current same like a. Need a pdf, regarding the electrical testing & commission !! This is the most asked Electrical Engineering Interview Questions in an interview. GATE 2021 Syllabus & Pattern, Best books, Previous Privacy Basic Electrical interview Questions & Answers paper-1 1.What is electricity ? The section contains questions and answers on capacitors, charge and voltage, capacitance, capacitors in parallel and series, electric fields, electric flux density, relative permittivity, composite dielectric capacitor, charging and discharging currents, growth and decay, cr networks transients, dielectric strength and displacement current, capacitor and capacitance types. The latching current is always greater than holding current. Answer: It can create shock hazards because the ON/OFF switch will cutoff only the neutral wire from the appliance connected to such outlets. In this page you can learn various important electrical engineering questions answers, mcq on electrical engineering, short questions and answers on electrical engineering,sloved electrical engineering objective questions answers for competitive exam etc. It is denoted by C & it is measured in Farads F. Inductance: inductance is the ability of a conductor to resist or oppose any change in the current. A transformer is essentially an inductor (coil) that has high inductance & low resistance. In today post, we will be sharing the frequently asked electrical engineering interview questions and answers related to electrical engineering. – Anyone preparing for aptitude test in Basic Electrical Engineering Thus these following methods are used for p.f correction (to nullify the lagging current), The capacitor helps in providing a leading current that eliminates the lagging component of current & improves the power factor. Apparent Power: It is the product of voltage & current without referencing the phase difference between them. A rectifier is an electronic circuit that converts the alternating current into a direct current. objective questions (MCQ) and answers you can download all notes below table. ALL RIGHTS RESERVED. Thus these following methods are used for. The cable charts provide this info such as voltage-drop per meter, current capacity, cable size, etc. Resistance Earthing; this is used to protect the equipment from fault condition by carrying the current through earth cable. And JTO Exams, Railways Jen And Section Engineers, DRDO, DMRC, Metro, many It is mostly used to reduce the flow of current. Your email address will not be published. motor has defined power factor (P.F) and the rating has been mentioned in kW or HP on Motor. They are used in logic-based circuit designing to process complicated functions like in computer & cellphones etc. Active power: it is the actual power that is delivered to the load such as transformer, induction motors, generators, etc and dissipated in the circuit. – Every MCQ set focuses on a specific topic in Basic Electrical Engineering Subject, Who should Practice these Basic Electrical Engineering Questions? Here’s list of Questions & Answers on Basic Electrical Engineering Subject covering 100+ topics: The section contains questions and answers on series circuits, parallel networks, power, energy, resistivity, temperature coefficient, kirchhoffs current and voltage laws. Electrical & Electronics Interview Questions & Answers. The section contains questions on kirchhoffs laws and network solutions, mesh and nodal analysis, superposition theorem, thevenins theorem, norton theorem, source transformations, maximum power transfer, delta star and star delta transformations. The insulation voltage or insulation level is the rated voltage of a cable at which the cable can withstand it for its lifespan without rupturing or breakdown. The holding current is the minimum current required to maintain the thyristor in forward conduction otherwise the thyristor will return to forward blocking state. Our website is made possible by displaying online advertisements to our visitors. you are preparing and searching SSC JE, GATE, IES, GATE Electrical Question Papers with Solution Difference Between Conductor, Semiconductor and Insulator, Difference Between Conductor and Superconductor, Difference Between a Transformer and an Induction Motor, Basic Electronics Engineering Interview Questions & Answers, Basic Electrical & Electronics Interview Questions & Answers, Electrical Engineering Questions & Answers, Electronics Engineering Questions Answers. A magnetic starter is a device designed to provide a safe starting method to electric motors with a heavy load. key, Website Is Not the Original A Passive network is a network that contains passive elements in its network such as Resistance, Capacitance, or Inductance whereas an Active Network is a network that contains active elements in its network such as Current or Voltage Sources. Thus, doubling the resistance will decrease the current by half. But practically it varies with the power factor of the load. it is operated when the power supply is off. © 2020 - EDUCBA. An instrument which detects electric current is known as, Enter the code above here : Our 1000+ Basic Electrical Engineering questions and answers focuses on all areas of Basic Electrical Engineering subject covering 100+ topics in Basic Electrical Engineering. A unilateral is a type of circuit whose properties change with the direction of current flow or the voltage. It has better conductivity & low weight as well as cost. The minimum initial current required to maintain thyristor in forward conduction state immediately after turning ON is called latching current. Mainly the transistor can be used for two reasons.
