An ammeter is a device used to measure electric current. A galvanometer is a sensitive instrument that detects small currents and deflects proportionally. To measure larger currents, the galvanometer's range is extended by using a shunt resistor connected in parallel. \omega t$ is passed through a moving coil and a moving iron ammeter which are in series. The reading of moving coil and moving iron ammeter will be respectively Ans: A GS&EI ElectEngg 14 2024 1601-2025 GS&EI ElectEngg 14 2024 1601-2025 Moving coil instruments are sensitive to DC current and respond to the average value. Moving iron instruments are AC devices that respond to the RMS value of the current.
A Galvanometer is converted into Ammeter by connecting the Shunt resistance in which way across the Galvanometer ?
