CUET and UG exam CUET UG 2025 Mock Test Series Physics Moving Charges and Magnetism The Moving Coil Galvanometer
A moving coil galvanometer is converted into an ammeter reads up to \(0.03\; \text{A}\) by connecting a shunt of resistance \(4r\) across it and ammeter reads up to \(0.06\; \text{A}\), when a shunt of resistance \(r\) is used. What is the maximum current which can be sent through this galvanometer if no shunt is used ?
1
\(0.04\; \text{A}\)
2
\(0.03\; \text{A}\)
3
\(0.02\; \text{A}\)
4
\(0.01\; \text{A}\)
