The current in electrical wiring has a frequency of 60 Hz. What is its speed?
Adh99
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.
Answer
Although 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.

What is the relationship between electrical frequency and magnetic field speed for an ac machine?
What is the relationship between electrical frequency and magnetic field speed for an ac machine
Does the frequency or wavelength of the wave affect its speed?
The speed of a wave depends only on the mechanical or electrical characteristics of the medium or environment through which the wave propagates. It doesn't depend on the wave's frequency or wavelength.
How does current flow in a conductor?
A conductor has a large number of free electrons which under sufficient voltage(electrical push) will flow in unison speed and direction. Thus creating a electrical current.
What is relationship between wave speed wavelenght and frequency?
Speed = (wavelength) x (frequency) Wavelength = (speed)/(frequency) Frquency = (speed)/(wavelength)
What is the correlation between wavelengths and frequency?
Wavelength = wave speed/frequency Frequency = wave speed/wavelength (Wavelength) x (Frequency) = Wave speed
If you increase or decrease the frequency what effect on electrical machin?
If you're talking about an electric motor, increasing the frequency will increase the speed of rotation of the motor, and decreasing the frequency will decrease the speed of rotation of the motor. The other way of controlling a motor is to control the current; increasing the current increases speed, decreasing current decreases speed.

What is the baud rate of a digital signal?
the digital signals frequency is infinite ,i.e ranges from 0.....infinity
What determines electrical supply frequency?
The speed of the alternators and the magnitude of the load.
What is meant by VFD?
A variable-frequency drive (VFD) is a system for controlling the speed of a rotational or linear alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor.[1][2][3] A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives.
What speed does electrical current travels?
At the speed of light- about 186,000 miles per second.
How can the frequency and voltage of an alternator be changed?
The frequency is changed by varying its speed, and the the voltage is changed by varying its field current.
Does the frequency or wavelength of the wave affect its speed?
The speed of a wave depends only on the mechanical or electrical characteristics of the medium or environment through which the wave propagates. It doesn't depend on the wave's frequency or wavelength.
What is VFD in electrical engineering?
it stands for Variable Frequency Drive. It uses either a local controller or an input signal to control the frequency or speed of a motor.
Is maths C needed for electrical engineering?
If you mean C as in the speed of light then I would assume yes. C is used to help calculate the current of electrical energy, which helps determine how much resistance in ohms must be used within wiring and also helps to establish wattage/voltage of electrical outlets, etc.
What is the purpose of a frequency converter?
A frequency converter converts "alternating current (AC) of one frequency to alternating current of another frequency." (Wikipedia) They are used to control the torque and speed of AC Motors. For more information go here: http://en.wikipedia.org/wiki/Frequency_changer.
What is the measurement for the speed at which an electrical current can do work is?
electricity travels at the speed of light +186,000 miles per second
