Question 247 of 404

The resistance of a galvanometer is 50 ohms and the current required to give full scale deflection is 100μA. In order to convert it into an ammeter, reading upto 10A, it is necessary to put a resistance of 

(1) 5×103Ω in parallel

(2) 5×104Ω in parallel

(3) 105Ω in series

(4) 99,950 Ω in series
