A voltmeter of range 2 V and resistance 300Ω cannot be converted into ammeter of range
Options
(a) 1A
(b) 1mA
(c) 100mA
(d) 10mA
Correct Answer:
1mA
Explanation:
Ig = (2 / 300) A = (2 / 300) × 1000 mA = (20 / 3) mA
Therefore, Ig = 6.67 mA
As range of ammeter cannot be decreased but can be increased only, therefore, the instrument cannot be converted to measure the range 1 mA.
