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

CHECK THE SOLUTION.
(5)
Sol. 
(G + 4990) = 30
⇒ G + 4990 = 
⇒ G = 10
×10 = 
⇒ S = 
⇒ n = 
= 5
