The same as the speed of light.

Answer

If you are asking how fast individual charge carriers move through a conductor, then the answer is that it is veryvery slow. So slow, in fact, that an individual electron is unlikely to travel the length of a flashlamp's filament during the lifetime of its battery! The actual speed is given by the following equation:

v = I/(nAe)

Where: v = velocity of electron (metres per second)

I = current (amperes)

n = number of electrons per cubic metre

A = cross-sectional area of conductor (square metres)

e = charge (coulombs)

Because full speed is unloaded. As you load the motor, speed decreases, and slip increases, with an accompanying increase in current.

The current in electrical wiring has a frequency of 60 Hz. What is its speed?

The speed of a current is about 2/3 the speed of light in a vacuum - in other words, the current travels at a speed of about 200,000 km/sec. This is independent of the frequency.AnswerAlthough the effect of an electric current is felt, more-or-less instantaneously along the length of a conductor, the individual charge carriers move very slowly in the direction of that current. In fact an individual electron is unlikely to travel the length of a flashlight's filament during the lifetime of its battery.
