It is making sense now. But in case of DC supply, since current moves in only one direction, all electrons will flow into the Earth and the source will be depleted of electrons, is it true?(In one of my above posts, i had asked that is it possible for bulb to glow when one of its wire is...

I actually am Instrumentation Engg. I have studied all these theories in shcool & colleges. But still i am confused. How i imagine this is power source is like a water tank and water should flow through the pipe (wires in our case) then flow through some instrument (like bulb in our case) and...

But in this case, with DC supply all electro in source will flow in Earth and the source will be depleted of electrons. What exactly happens? (In AC and DC also) please explain.

@Davenn As you said my experiment will work in case of home power supply. So does it mean current flows all the way back to neutral terminal of source (power station) through ground? But in case of car battery even if i provide Earth connection the negative terminal will not have any...

@Davenn Thanks a lot for your clear answer :)

Thanks for your answer! But now i have another question :)...that's what always happens with me! If current can flow in open path then is it possible that a bulb will glow when the wire coming out from +ve terminal is connected to one terminal of the bulb and other wire coming out from...

I know that current can flow in loop only. I mean circuit must be complete for current to flow. So my question is: If someone is hanging in the air holding power transmission line, he doesn't get shock. Because circuit is incomplete. But if he touches ground in same position then he receives...

I find EM waves very intriguing. But i get more confused and new questions pop up in my head every time i read something about it. I have a few basic questions. 1. Wavelength: As wavelength is distance between two peaks, how can we measure this distance in cm, meter etc. as physically there...

Is the shape of a pixel always square is inherent to the screen? and when a picture of higher resolution is viewed on screen with lower resolution, o pixel shrink to fit in the screen? Since no. of pixels on the screen (max resolution) are fixed how a image or video of different resolution is...

A pixel is said to be an intersection between horizontal and vertical lines on the screen. So does this intersection have a physical shape and size and what happens when an image or video of say 1600X1200 is played on screen having resolution of 800X600 or vice versa. I have searched a...

In electromagnetic spectrum, frequency & wavelength differentiate between radio waves and light waves. So, if the frequency of the radio wave being transmitted by a tower is changed to match the frequency of the visible light, will tower start emanating light?

Thanks for the replies! The image below might help to explain my imagination http://www.mds975.co.uk/Images/radwave1.jpeg In above image, suppose there is transmitter on left side and receiver on the right. In between is the wave. Is this how the EM waves travels in air? If we could then we...

How the wavelength of wave is measured? My idea of electromagnetic wave is there is an invisible line traveling through space moving up and down like a sine wave we see on CRO. Is this idea correct? Or is it the the variation in electric and magnetic field of the wave that we relate this...

Frequency & Wavelenght of EM wave! Hi..on some other thread i found this link showing animation of propagation EM wave: http://www.molphys.leidenuniv.nl/monos/smo/index.html?basics/light_anim.htm it has cleared my one doubt, because i used to think that EM wave is like an invisible line...

@sophiecentaur Thanks a lot. That really cleared my confusion.
