6. 11th Class Physics Lecture | Current Electricity | Drift Velocity of Free Electrons (GA)

let us study about drift velocity of free electrons. we have discussed that in the situation of conductor when, a battery is connected across it. and, the circuit is closed. You can just have a look on the situation i am drawing here. this a battery which is connected across cylindrical conductors wire switch. as […]

12. Class 12 Physics | Current Electricity | Circuit Symbol of a Resistance & Equations of Ohm’s Law

let us discuss about circuit symbol of resistance and equation of ohms law. i hope all of you aware about that in. electrical circuit, resistance is represented by a zigzag line. say if there are 2 terminals ay and b. across which resistance r is connected. and say if, at terminal ay potential is v-a […]

Porous electrodes

So next what I want to show you, when you have porous electrode, how does the impedance vary. Within the domain of porous electrode there are lot of possibilities, what we are going to see is basically only one example and after that if time permits we will go on to look at what happens […]

hello I’m Alberto patashnik I’m the director of the agency for the cooperation of energy regulators I’m also an advisor with the flooring school of regulation and I’ve been an advisor here for many years since the very early days of the school what I’m going to present today and introductory some introductory ideas on […]

Review of all Electricity and Magnetism Dimensions – AP Physics C

Bo: Hey guys. Billy: Hey Bo. Bobby: Hi Bo. ♫ (lyrics) Flipping Physics ♫ Mr. P.: Ladies and gentle people, the bell has rung, therefore class has begun. Therefore you should be seated in your seat and ready to review electricity and magnetism dimensions, because dimensions are your? Billy, Bobby, Bo: Friends. Mr. P.: That’s […]

How do wind turbines generate electricity? – IN 60 SECONDS

How do offshore wind turbines generate electricity? You probably know that wind turbines produce electricity from wind. But how do they do it Let’s take a look at this particular offshore wind turbine. Sensors on top of the turbine measure wind speed and direction They signal the yaw-motors in which direction to turn in order […]

5. Class 12th Physics | Current Electricity | Solved Example-2 on Current Electricity | Ashish Arora

in this example we are given that in a long wire of square cross section of side length l. current density varies with distance from one edge of cross section as j is equal to ay e to power b-x amp-ere per meter square. where ay and b are positive constant and we are required […]
