When a current of 5 mA is passed through a galvanometer having a coil of resistance 15Ω, it shows full scale deflection. The value of the resistance to be put in series with the galvanometer to convert it into a voltmeter of range 0- 10 V is
(a) 2.045x103Ω (b) 2.535x103Ω (c) 4.005x103Ω (d) 1.985x103Ω
