Electric Charges & Fields | Concepts, Derivations & NCERT Solutions Class 12
Chapter One: ELECTRIC CHARGES AND FIELDS Here are the main points from the provided sources on electric charges and fields, organized with headings and subheadings: Chapter One: Electric Charges and Fields 1.1 Introduction Many common phenomena, such as sparks or crackles from synthetic clothes in dry weather, lightning during thunderstorms, or electric shocks when touching a car door, are due to the discharge of electric charges accumulated through the rubbing of insulating surfaces. This phenomenon is related to the generation of static electricity. Static refers to anything that does not move or change with time. Electrostatics is the study of forces, fields, and potentials that arise from static charges. 1.2 Electric Charge Historical Discovery: The discovery that amber, when rubbed with wool or silk, attracts light objects is credited to Thales of Miletus, Greece, around 600 BC. The word "electricity" is derived from the Greek word "elektron," mea...
