Electric charges and fields :- Notes

Notes :- Hey Guys!! Here i am providing you notes of chapter 1 class 12th physics.. These are notes of what I taught in youtube videos.. so that you can revise your concepts accordingly… These are the notes of Electric charges and fields (from Electrostatics).. Hope this may help you… 😊 Electrostatic - charges at rest. {study of charges when charges are static(at rest) }. Electric Charges - Intrinsic property of a matter. Origin - Around 600BC -Thales of melatus, Greece Types of charges - To distinguish different charges Benjamin Franklin gave polarity - positive charge and negative charge. How is a charge created??? By friction (Rubbing) - When two objects rubbed together they generate energy and loosely bounded electrons are removed. Object from which electrons are removed .. becomes positively charged. Object which gains electrons becomes negatively char

Question Bank- Electrostatic Potential & Capacitance

Important questions of Chapter-2 class 12th Electrostatic Potential and Capacitance Questions on Electric potential, potential difference and work. Q . 1 The potential difference between two points is 10 V how much work will be done in carrying a charge of 200 µC from one point to the other point. Ans. 2 x 10^-3J Q . 2 What is the electric potential at the surface of a gold nucleus of diameter 13.2 fermi. Z for gold is 79. Ans. 1.7 x 10^7 volt. Q .3 If 20 J of work has to be done to move an electric charge of 4 C from a point, where potential is 10 V to another point, where potential is V volt, find the value of V. Ans. 15V . Q .4 The electric potential at 0.1 m from a point charge is +50 V. What is the magnitude and sign of the charge. Ans. 0.55 x 10^ -9 C and positive. Q .5 A wire is bent in a circle of radius 10 cm it is given a charge of 250 µC which spreads on it uniformly. What is the electric potential at Cen

Electromagnetic Spectrum

Electromagnetic Spectrum 1) Radiowaves - Range - 5 x 10^5 Hz to 10^9 Hz Produced by - oscillating electric circuits having an inductor and capacitor Properties - 1) Travel with speed of 3x10^8 m/s 2) Obey laws of reflection and refraction 3) Get diffracted from obstacles coming in their path Applications /Uses- 1) wireless communication purposes, transmit radio and TV signals 2) Used in radio astronomy 2) Microwaves - Range - 1GHz to 300 GHz Produced by- special vaccum tubes, namely klystrons,magnetrons, Gunn diodes etc Property - Produce heat, when absorbed by matter Uses - 1) In radar systems. 2) In long distance telephone communication system 3) Used for cooking 4) In study of atomic and molecular structure 5) Used for observing the movement of trains on rails while sitting in microwave operated control rooms. 3) Infrared ( sometimes called heat waves) Range - 3x 10^11 Hz to 4 x 10^14 Hz Discovered by - Herschell Produced by
