Problem
A galvanometer having a coil resistance 100Ω gives a full scale deflection when a current of 1 mA is passed through it. What is the value of the resistance which can convert this galvanometer into a voltmeter giving full scale deflection for a potential difference of 10 V?
(1) 10kΩ
(2) 8.9kΩ
(3) 7.9kΩ
(4) 9.9kΩ
