10 Simple Quizzes on Electric Current Objective Type Questions

electric_currentElectric current is a flow of electric charge through a medium is measured as the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes.  Electric current is measured using an ammeter.The standard abbreviations for the units of current  are 1 A = 1C/s. This charge is typically carried by moving electrons in a conductor such as wire. It can also be carried by ions in an electrolyte, or by both ions and electrons in a plasma.
