How does current flow in an AC circuit?
The electrons in an AC circuit don’t really move along with the current flow. Instead, they sort of sit and wiggle back and forth. Alternating current works in much the same way. The electrons initially move in one direction, but then reverse themselves and move in the other direction.
How are inductors different for the cases of AC and DC current?
In other words, the inductor is a component that allows DC, but not AC, to flow through it. The inductor stores electrical energy in the form of magnetic energy. The inductor does not allow AC to flow through it, but does allow DC to flow through it.
Why is an alternating current induced in the coil?
As one side of the coil moves up through the magnetic field , a current is induced in one direction. As the rotation continues and that side of the coil moves down, the induced current reverses direction. This means that the generator produces a current that is constantly changing. This is alternating current or a.c.
Does AC current have positive and negative?
Conventional current flows from the positive pole (terminal) to the negative pole. Electrons flow from negative to positive. In an alternating current (AC) circuit the two poles alternate between negative and positive and the direction of the current (electron flow) reverses periodically.
How fast is AC current?
Its about 300 million meters per second. The propagation of electric field, or electrical signalling using electrical signals in a wire is a bit slower.
How can you differentiate AC circuit and DC circuit explain how inductor and capacitor responds behave to AC and DC voltages?
So after gets fully charges it is open circuit. So Capacitor act as open circuit element. But in AC source, Voltage is a variable, so it continuously charge-discharge- charge. So, for a DC source, Current is constant, So Inductor act as short circuit element and for a AC source, Inductor act as a resistor.
How are inductors different for the cases of AC and DC current How are inductors similar and different to capacitors?
What is this? Capacitors store energy in an electric field. Inductors store energy in a magnetic field. In a capacitor, energy is calculated in terms of voltage….Table of Differences between Capacitors and Inductors.
| Feature | Capacitor | Inductor |
|---|---|---|
| DC Current | Current Decreases Over Time | Current Increases Over Time |
How does an alternating potential difference create an alternating current?
The alternator As one side of the coil moves up through the magnetic field, a potential difference is induced (created) in one direction. This means that the alternator produces a current that is constantly changing. This is alternating current or ac.
What speed does an AC generator rotate?
An induction generator produces electrical power when its rotor is turned faster than the synchronous speed. For a typical four-pole motor (two pairs of poles on stator) operating on a 60 Hz electrical grid, the synchronous speed is 1800 rotations per minute (rpm).
