Explanation:
the question is wrong......
completely wrong...
below given is the answer given by a scientist MichaEl Williams
There is a simple answer and a complicated answer.
Simple - no. The electrons in a wire that form the electric current move very slowly. The second hand on a watch moves faster than the electrons. The actual speed of electrons is about 1.2 inches per minute in a typical, home lighting circuit.
Complicated - The effect, or electromagnetic wave, of electric current moves at nearly, but not quite, the speed of light.
Think of a tube full of balls. If you push one more ball into the tube, the ball at the other end comes out immediately. This is why turning on a light switch has an immediate effect. The electrons in the wire all push on each other and thus the light goes on instantly.
In theory, electricity moves at the speed of light and in practical application, this is true.
However, in practice it is slightly slower because the electron from atom #1 has to cross the space to atom #2 in order to bump its electron over to atom #3 in the wire. This tiny delay adds up over very long distances and the speed of electricity over millions of miles turns out to be very close, but not quite the speed of light.
