MCQs on Electric Current Questions and Answers

Current – Definition

The definition of electric current is flow of electrons or movement of electric charge. The SI unit of current is ampere. Current can be alternating (AC) or (DC). The symbol of current is I. The term current introduced by Danish Physicist Hans Christian Oersted in 1820. All the MCQs on Electric Current Questions and Answers are published according to the new study syllabus for academic year 2021-22.

The aim is to provide Electric Current MCQs Multiple Choice questions and answers to understand the concepts of Electricity. 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 current. If you are a students, technician or teacher then you can learn the basic concept of electric current applications, principle and function.
