Welcome Class 10 students! Here's your complete, easy-to-understand blog-style guide to CBSE Physics Chapter 1 – Electricity . It covers definitions, formulas, SI units, laws, and numerical tips to ace your exams confidently. π§ π π What is Electricity? Electricity is the flow of electric charge (electrons) through a conductor, like copper wire. Electric Current (I) : The amount of charge (Q) flowing through a conductor in 1 second. Formula : I = Q / t Where: I = current (Ampere, A) Q = charge (Coulomb, C) t = time (seconds) π Potential Difference (V) It is the work done to move a unit charge from one point to another. Formula : V = W / Q Where: V = potential difference (Volts, V) W = work done (Joules, J) Q = charge (Coulomb, C) Instrument Used : Voltmeter (always connected in parallel) π₯ Ohm’s Law The electric current flowing through a conductor is directly proportional to the potential difference , provided temperature remains ...
