Ammeter Question & AnswersApril 3, 2023 By Wat Electrical This article lists 75 Ammeter MCQs for engineering students. All the Ammeter Questions & Answers below include a hint and a link to the relevant topic wherever possible. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of the Ammeter.An instrument that measures either direct or alternate currents is referred to as Ammeter. The current measured through these devices is of a wider range. For higher values, only the smaller current portion gets directed through the meter. The shunt placed with the meter in a parallel way carries major portions. Earlier the ammeters used to be in labs for operations and rely on Earth's magnetic field. Further, the improvements made in the circuits of ammeters such that mounting in any position can provide the measurements accurately using an electric-power system.There is a relation between physical force, magnetic field, and electric currents. This is noticed by Hans Christian Orsted for the first time in the year 1820 from the needle of the compass deflecting from the North point when the flow of current is in the adjacent wire.Tangent galvanometers are utilized for measuring current using the technique mentioned. But these instruments can measure current when aligned on Earth's magnetic field. But Ammeters provide ease while measuring currents. These instruments are placed in a circuit in series and the current values can be measured. 1). Which device is used to measure current? Voltmeter Ohmmeter Ammeter Magnetometer None Hint2).
