Web6 sep. 2024 · How do you increase the range of an ammeter to N times? To increase the range of an ammeter to n times, the value of shunt reuired is ( G = resistance of galvanometer ) 1. G / n. 2. Why do we need to extend range of an ammeter? For example, a moving coil ammeter can measure currents 0-100mA. WebBy connecting a suitably low resistance parallel to the ammeter, the ammeter's range can be expanded. Thus, the effective resistance is decreased. The current flow through the ammeter is increased when the resistance is reduced. Hence, this is the way to increase the range of an ammeter. Suggest Corrections 1 Similar questions
