Q.31 A student uses a battery of adjustable voltage 0-6 V. She has to perform an experiment 
to determine the equivalent resist5ance of two resistors when connected in parallel 
using two resistors of value 3 ? and 5 ? . The best choice of combination of voltmeter and 
ammeter to be used in the experiment is : 
(a) Ammeter of range 0-5A and Voltmeter of range 0.10V 
(b) Ammeter of range 0-5A and Voltmeter of range 0-5V
