The actual direction of the electron flow (= current = electron stream) in an ac circuit is reversing 50 times per second. (or maybe 60/s in your country.)
Remember, the speed of the current flow, the electrons will be a significant part of the speed of light.* So it can reverse flow in the whole circuit. Light travels 300 000 000 m/s. (~186 000 miles/s)
Therefore in 1/50 of a second, it will travel 300 000 000/50 = 6 000 000 metres = 6000 km.
* Actually, electricity in a wire will travel at .7 or so of the speed of tight.
AnswerCurrent flow in 50-Hz system reverses direction 100 times per second, whereas the current in a 60-Hz system reverses direction 120 times per second.
D.C. current flow is extremely slow, although its effect is practically instananeous. Depending on the size of the conductor, it is typically measured in millimetres per hour -an electron in a flashlight lamp is unlikely to travel through the filament during the lifetime of the battery.
What else can I help you with?
What is the waveform of AC through a straight wire?
Either sinusoidal, or can always be represented as a sum of sinusoids.
Am transmitter working principle?
even a single wire can tansmitam signal in which ac signal pass through it
What is the result when AC flows through a straight wire?
power loss will be more in heating of the wire.powertransit is directly proportional to thesquirof the circumference.
Can you by pass the AC pressure switch?
If it is a 2-wire switch- yes If it is a 3-wire switch- no
Can ac pass through capacitor?
AC can pass through a capacitor. The higher the frequency of AC the lower the reactance (like resistance). The current and applied voltage are 90 degrees out of phase the current leading the voltage by this amount.
What is ac ground?
If a circuit is grounded through a capacitor it is referred to as AC ground because ac signal can pass through the capacitor DC level is blocked
What type of magnetic field do you get around the wire when an ac supply passes through it?
You get building a collapsing eddy currents that alternate in direction. The placing of another wire in this field will cause a current to be generated in the second wire. That is the basis of transformers.
Why you using DC power supply for capacitor?
Because it does not allow ac to pass through it...
How does ac current move in a wire?
AC current moves in a wire by periodically reversing direction, flowing back and forth in response to the alternating voltage source. The electrons in the wire oscillate back and forth, creating an electric field that propagates through the wire and carries the energy along with it.
Does a Cpacitor allow ac to pass through it?
no capacitor does not allow ac component .if allow then inductor allow dc component .
What is the recommended wire size for an AC unit installation?
The recommended wire size for an AC unit installation is typically 10-gauge wire.
Why does a wire begin to vibrate when ac is passed through it?
When AC (alternating current) is passed through a wire, the current flow changes direction periodically. This change in current flow causes the wire to experience an electromagnetic force that makes it move back and forth, creating vibrations. These vibrations are more pronounced at certain frequencies because of resonance effects.
