The answer of this question is option C . I understand the reason behind opting the ammeter of range 0-2 A. But why is the voltmeter range 0-10 v ? Q.1 A student uses a battery of adjustable voltage 0-6V she has to perform an experiment to determine the equivalent resistance of two resistors when connected in parallel using two two resistors of value 3 ohm and 5 ohm the best choice of combination of voltmeter and ammeter to be used in the experiment is (c) ammeter of range 0-2 A and voltmeter of range 0-10 V ?
