A galvanometer gives full scale deflection with 0.006 A current. By connecting it to a 4990
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
Text Solution
Verified by ExpertsThe correct answer is:
5
(5)



R=10



Since R G and R S are in parallel, i G R G = i S R S
0.006R=1.494 
n = 5
