Question

When you ip a light switch, the light turns on almost immediately. Why is this? (1 pt.) A) the electrons themselves move at nearly the speed of light B) current is owing at all times in the circuit, even when the switch is o C) the signal that tells the electrons to begin moving moves at the speed of light D) the electrons themselves don't move at the speed of light, but do move at a rate fast enough that we don't notice the delay E) none of the above

Explanation / Answer

While the electrons themselves have a low drift speed, they start moving everywhere simultaneously the moment a potential difference is established.
The correct option is
E) none of the above
