State Ohm's law. Express it mathematically. Define SI unit of resistance

Ohm’s law states that at a constant temperature and physical conditions, the current is directly proportional to the potential difference. Ohm’s Law can be represented mathematically by –

V = IR

Where,

V is the potential difference
I is the current
R is the resistance

The SI unit of resistance is the ohm.

An astronomical telescope consists of two converging lenses. One of them of large aperture and large focal length is called objective lens and the other one, of smaller focal length and smaller aperture is called the eyepiece. It is used to see distant objects which are not seen clearly with naked eyes. The image formed by the objective lens acts as an object for the eyepiece and the final image produced by the eyepiece is magnified.
