What is the speed of current when the bulb lighted up? And what is the speed of light? Is light faster than current or current is faster than light?
The speed of light in vacuum is greater than everything else in this universe.
The electrical signal when the bulb is lighted up will travel at a speed close to the speed of light, but not more than the speed of light.
