Can we increase the range of a telescope by increasing the aperture of the objective?

How does magnifying power of a telescope change on decreasing the aperture of its objective lens?Justify your answer.

Define the term resolving power of an astronomical telescope.How does it get affeted on increasjing the aperture of the objective lens?

Explain with reason,how the resolving power of an astronomical telescoe will change when aperture of the objective lens is halved.

Can we increase/decrease the range of a given ammeter?

Can we increase/decrease the range of a given voltmeter?

Explain with reasons,how the resolving power of a compound microscope will change when aperture of the objective lens is increased.

To increse magnifying power of telescope,we sould increase:

Explain with reason,how the resolving power of an astronomical telescoe will change when focal length of the objective lens is increased and

How does the resolving power of a compound microscope get affected on increasing the focal length of its objective?

In a telescope the image is actually not magnified but telescope simply increases the visual angle of the object. (Yes/No)
