Vernier caliper

Introduction

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.

Charge Density Formulas and Solved Example

In this article, we would learn about charge density and its formulas and would also solve some problems related to this concept. We encounter electric charge density while calculating electric field from various continuous charge distributions like linear, surface and volume. We also need the concept of charge density while studying current electricity. What is Charge Density?
