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 ?

Pls explain how the answer is option c:

1. A Student uses a baterry of adjustable voltage 0-6V. She has to perform an experiment to determine the equivalent resistance of two resistors when connect in parallel using two resistors of value 3 Ω and 5 Ω. The best choice of combination of voltmeter and ammeter to be used in the experiment is.

(c) Ammeter of range 0-2A and voltmeter or range 0-10v.

↵A student uses a battery of adjustable range 0-6V. . She has to perform an experiment to determine the equivalent resistance of two resistors when connected in parallel using two resistors of value of 3ohm and 5ohm. The best choice of combination of voltmeter and ammeter to be used in this experiment is :
(a) ammeter of range 0-5A and voltmeter of range 0-10V
(b)Ammeter of 0-5A and voltmeter of 0-5V (c)Ammeter of 0-2A and voltmeter of 0-10V (d)Ammeter of 0-5A and voltmeter of 0-2V
