What statement descibes the flow of electic current in an AC circuit?
The flow of electric current in an AC circuit is alternating, it flows one way then the other, with reference to ground.
What happened to electron under ac voltage and dc voltage?
when electrons flow under AC they flow in both direction firstly forward then in reverse and it does this for as long as there is a potential difference applied to the circuit. under DC the current only flows in one direction only
Why neutral wire does not carry current in closed ac circuit?
The neutral wire does carry current in a closed AC circuit. Clamp a clamp on amp meter around the neutral wire directly after the circuit load and it will read the same current as is on the "hot" wire.
How do appliances work if AC reverses direction?
AC current alternates polarity back-and-forth continually, by definition. Therefore, it is not possible to reverse AC direction. It is DC current that is directional such that when it's polarity is reversed the motor responds by turning in the opposite direction.
What is the direction of the current?
Current flows from negative to positive for DC. AC the direction changes with the sinewave. eg. AC a frequency of 60Hz the direction changes 120 times.
When current in a circuit reverses its direction in a regular pattern it is called?
An "Alternating Current" (AC).
What is the difference between DC and AC?
The primary difference between DC and AC is the direction of current flow. In a DC circuit, all electron current flow is in one direction. In an AC circuit, current flows in one direction for part of the time, and in another direction for another part of the time. In the AC circuit, we'll see current flowing "back and forth" instead of the unidirectional current flow we find in a DC circuit.DC is "Direct Current", and AC is "Alternating Current". In DC, the current flow is in one direction only. In AC, the current flow is constantly changing direction.An example of DC is the output of a battery. An example of AC is the power present in a home electrical system.The current whose magnitude and direction remains change called as alternating current.The current whose magnitude and direction remain unchanged called as d.c. Current.
What does AC and DC stand for in electrical field?
Alternating Current and Direct Current. Electricity is voltage and current. Voltage is electrical pressure, and current is the flow of charged particles. The difference between alternating current (AC) and direct current (DC) is that the electrons in an AC circuit regularly reverse their direction. In a DC circuit electrons always flow in the same direction.

In which circuit does charge reverse direction many times per second?
In an alternating current (AC) circuit, the electric charge periodically reverses direction at a certain frequency. This is in contrast to a direct current (DC) circuit, in which charge flows in one direction only.
Why inductor block ac and pass dc?
When your circuit starts up, your inductor creates an electrical current in the opposite direction. With dc, this effect vanished after the circuit is started. With ac, the current keeps starting and stopping so the inductor keeps creating a current in the opposite direction.
How does the direction of an electrical circuit move on a battery device differ from the direction of an ac current?
In a DC circuit (battery), the lower potential is always on one 'end' of the circuit so the current always flows in the same direction. In a AC circuit, a wave is generated so each end cycles between high and low potential. Current always flows towards lower potential and changes direction every time the higher/ lower potential changes
What current flows in one direction then the opposite direction?
AC, Alternating Current.
Why should current be reversed in an AC circuit?
The current in any AC circuit reverses every cycle.
What is the difference between altenating current and direct current?
The current (or electrons if you will {but thought of as flowing in the opposite direction} in a DC circuit flows only in one direction. In an AC circuit the current periodically flows in the opposite direction (in the US this usually happens 120 times a second, so 60 cycles per second.)
What is direct and alternating voltage?
An alternating current (AC) is an electric current whose direction reverses cyclically, as opposed to direct current, whose direction remains constant. The usual waveform of an AC power circuit is a sine wave, as this results in the most efficient transmission of energy.
Does a diode block ac or DC?
A diode blocks current flowing in one direction, and passes a current going into the other direction (with a little potential energy loss). DC is a current flowing into one direction all the time. therefore if you put a diode in a dc circuit it will either always block or always let it pass (provided a certain amount of supply voltage). if you have an ac circuit the current alternates (ac=alternating current) most of the cases the current flows half of the time in one direction and half of the time into the other direction. so you will have both cases 50% blocking 50% passing through. so if you put an LED into an ac circuit, no matter what way you put it in you will always see light.
