Definition of Resonance Circuit
To understand the phenomena of Resonance, it is important to tune LC circuit on a frequency in which the value of XL (Inductive Reactance) becomes equal to the XC (Capacitive Reactance).The frequency on which Inductive Reactance and Capacitive Reactance becomes equals (XC=XL) that is called Resonant Frequency. Resonance Effect is also called tuning effect. The Resonance Circuits are used in all the Electrical and Electronics circuits. All the MCQs on Resonance Circuit are published according to the new study syllabus for academic year 2021-22.
The aim is to provide Resonance MCQs objective questions and answers to understand the concepts of Resonant. If you are willing to learn the concepts of Basic Electronics MCQs multiple choice questions with answer then read all the questions and answers. You will be surely able to qualify for all kinds of Quiz / tests / Interviews after understanding the Introduction to Resonance. If you are a students, technician or teacher then you can learn the basic concept of Resonance applications, principle and function.
