Energy & Electricity in Science : How Does Wave Energy Work?

Hi, I’m Steve Jones and I’m going to tell you a little about how wave energy works. The first thing to understand this, that the energy comes from the movement of the wave as the wave goes past the point through a various different types of energy that can be harness in this way, but […]

1. Physics Lecture of 11th Class | Current Electricity | Electric Current | by Ashish Arora (GA)

dear students lets start with the topic of electric current. and, in your early classes you might have studied about the basic definition of current in which, we write that. rate of flow of charge. through. any cross section. of a conductor. in which current is flowing obviously we are talking about. is called. electric […]

Energy & Electricity in Science : How Does an Electric Motor Work?

Hi, I’m Steve Jones and I’m going to explain how an electric motor works. Now I’ve drawn this diagram, it looks rather complicated but it isn’t really that complicated. There are two main elements. The first is this pair of magnets, one with a north here, the other with a south here. These are usually […]

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 […]

Energy & Electricity in Science : How Does Electricity Light Up a Bulb?

Hi, I’m Steve Jones and I’m going to tell you how electricity lights up a bulb. Well, the bulb doesn’t really light up unless there is a coating on it, it is the filament inside which lights up and the filament is made usually of something called tungsten which is a very hard material and […]

Energy & Electricity in Science : How Does an Electric Circuit Work?

Hi I’m Steve Jones and I’m going to explain how an electric circuit works. Well first of all we have to remember that there are certain things which conduct electricity which we call conductors and there are others which don’t conduct which are called insulators. Now conductors and insulators you must know the difference between […]

EQUIVALENT RESISTANCE 3 | VERTICAL SYMMETRY | Hindi | English Subtitles [CC]

Now let’s talk about vertical symmetry Now you can see that vertically this figure is symmetrical If we draw a line like this both halves will be symmetrical vertical symmetry is present when a mirror divides the circuit in such a way to produce mirror images and “a” & “b” lies on the opposite sides […]

18. Physics | Current Electricity | Electromotive Force (EMF) | by Ashish Arora (GA)

let us study about electromotive force. this is term which is also abbreviated as e m f. and now onward we are going to use the term e m f, very frequently, in this chapter, as well as in the, coming topics. about e m f we can write that. any devices. which can. continuously. […]
