Can the frictional electricity produced during landing of a plane be used for constructive purposes?

As we know that in aeroplane during landing the charged produced in it due to the friction with ground are earthed through its wheels; can this charge be stored with the help of a capacitor and used for useful purpose? Answer: I feel that this is a metter for research. If you feel otherwise and…… Continue reading Can the frictional electricity produced during landing of a plane be used for constructive purposes?

Why does a moving train drag us when near?

When we are near the moving train,we feel that the train drags us,,,  at the same time when we are near the window side in the moving train,y the plants or trees which is near the railway track get outward movement or repel from us? plz explain which concept behind this act? Asks Babu. The…… Continue reading Why does a moving train drag us when near?

Doubts on electric field lines and flux

Q1.Is the number of electric feild lines due to a charge DEFINITE? Q2.If it is infinite, then the electric flux due to a charge should be infinite(flux gives the num. Of elctric feild lines passing through an area)? AND Flux should be equal irrespective of the magnitude of charge. Q3.If it is definite,then it will…… Continue reading Doubts on electric field lines and flux

What does a rheostat control?

What does Rheostat controls? electron drift velocity or quantity of electrons? We know I=nAve I=current n=quantity of electron A=conductor area e=electron charge v=drift velocity (Asked  Partha)
