Question

Voltmeter of range 2V and resistance 300 ohm cannot be converted into ammeter of range

Answer 1

Answer:

1 mA

Explanation:

Ig=2300A  

=2300×1000mA  

=203mA  

Ig=6.67mA  

As range of ammeter cannot be decreased but can be increased only, therefore, the instrument cannot be converted to measure the range 1 mA

Answer 2

Answer:

v=ir,v=2v,r=300omh

Explanation:

i=(0.0067/1000)=6.67mAh   (ans)
