A galvanometer gives full scale deflection with 0.006 A curren

Question

Hard

Solving time: 4 mins

A galvanometer gives full scale deflection with $0.006$ A current. By connecting it to a $4990Ω$ resistance, it can be converted into a voltmeter of range $0 - 30 V$ . If connected to a $\frac{2 n}{249} Ω$ resistance, it becomes an ammeter of range 0-1.5 A. The value of $n$ is......
