Ohm’s Law Verification

We already know the statement of Ohm’s Law which is

“If the physical state of the conductor (Temperature and mechanical strain etc.) remains unchanged, then current flowing through a conductor is always directly proportional to the potential difference across the two ends of the conductor”

Escape Velocity Formula

TL;DRThe escape velocity formula does not depend on the escaping object’s properties. The only thing that counts is the celestial body’s mass and radius. It is given by the relation$v_e = \sqrt{\frac{2GM}{R}}$ You’ve probably seen rockets launch into space. These rockets need a huge kick or push to leave the earth’s surface. This push is …

Vernier caliper


Vernier caliper is introduced in 1631 by Pierre Vernier of France.It is instrument for making very accurate linear measurements It utilizes two graduated scales: a main scale similar to that on a ruler and an especially graduated auxiliary scale, the vernier, that slides parallel to the main scale and enables readings to be made to a fraction of a division on the main scale.
