Top 10 Basic Electrical Engineering Questions Part 1 What do you mean by SPICE? SPICE is an acronym for Simulation Program with Integrated Circuit Emphasis. Simulation software programs solves problems by simulating the behavior of electrical and electronic circuit components rather than by solving sets of equations. Two of the most popular simulation softwares are … Read more
Question: What is the loading effect of Electrical measurement instruments? Answer: The loading effect is the degree to which a measurement instrument impacts electrical properties (voltage, current, resistance) of a circuit. Loading Effect Formula: Loading Effect in Electrical Measurements Loading effect of voltmeters A voltmeter always connects in parallel to the electrical components for measuring … Read more
A transformer helps move electricity from one location to another. During its working, a transformer may vibrate or shake a little, and that tiny movement can cause a humming noise. The buzzing sound commonly heard from transformers or fluorescent light ballasts is caused by a phenomenon known as magnetostriction. This effect is a result of … Read more
Question: Why and where a condenser is installed in a steam power station? Answer: A condenser is installed next to turbine exhaust. Exhaust steam from turbine enters the condenser where the condensate is recovered and is used as boiler water. Schematic diagram of the condenser Advantages of condenser It recovers re-useable condensate which is fed … Read more
In a steam power station, coal is stored in a coal storage plant. After that coal is delivered to the coal handling plant where it is pulverized. The term pulverization means to reduce or to convert to fine particles. The pulverization of coal (crushing into small pieces) is done in order to increase its surface … Read more
What are Lighting Arrestors A lightning arrester or a surge diverter is a protection device which conducts the high voltage surges on the power system to the ground. Given below are five types of Lightning Arrestor The video below explains in details the working of lightning arresters:
