Surfe is inside a computer, the electricity is moving in a CIRCUIT OR A MOTHERBOARD 😂The speed of electric current
Since nothing visibly moves when the charge-sea flows, we cannot measure the speed of its flow by eye. Instead we do it by making some assumptions and doing a calculation. Let's say we have an electric current in normal lamp cord connected to bright light bulb. The electric current works out to be a flow of approximatly 3 inches per hour. Very slow!Here's how I worked out that value. I know:
Bulb power: about 100 watts, about 100V at 1A
Value for electric current: I = 1 ampere
Wire diameter: D = 2/10 cm, radius R=.1cm
Mobile electrons per cc (for copper, if 1 per atom): Q = 8.5*10^+22
Charge per electron: e = 1.6*10^-19
The equation:cm/sec = ________I_______ = .0023 cm/sec = 8.4 cm/hour
Q * e * R^2 * piI will be kind with your feat and say that it was moving faster than 3 inches per hour, BUT NOT THE SPEED OF LIGHT.
Electrical Current does not move that fast in wire
ALSO: THE SPEED OF THE CHARGES IS PROPORTIONAL TO THE VALUE OF ELECTRIC CURRENT
I know that the general conception is that electricity moves through wires at slightly less than the speed of light through wires. Whether that's a common misconception is something I've not seen definitively cemented.
But that electrical/electronic signal is not moving at 3 inches per hour. And it's not even moving through a wire (as far as I can tell).
