Line 24: − '''''Response 1:'''''Electrical current is a measure of the amount of electrical charge transferred per unit time. It represents the flow of electrons through a conductive material. The direction of electric current is opposite to the direction of electrons. + − − '''''Response 2:'''''It will be more apropriate to say that the electric field moves instead of the electrons. _ The electric current is- The movement of the electric field in the conductor not the electrons. We know that electricity almost moves in the speed of light. At this speed the electrons would get such a momentum that a small bent in the conductor, is enough to make electron to get out of the path because of inertia of linear motion. Think about it.( Needs discussion) − − '''''Response 3:''''' One way to think of this is to think of the electric field as an information field. − − Let us say we are in a large hall with a few exit doors. Once a programme is over everyone gets up and attempts to move towards the nearest exit. It is not that everyone gets up one after the other and goes to the door. The information to get up and move is communicated simultaneously. Similarly it is not that the tubelight glows because the electrons move from one end to another. We know that the drift velocity of the electrons is different and this is not what we call current. Rather information about how the electrons can move is communicated when the potential difference is applied. And this information travels at the speed of light. − − Instead of electricity, it may be more accurate to say that the information is communicated across the electric field at the speed of light. − − This understanding of the "field" concept as an information field is crucial to the understanding of electromagnetism.
