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 direction does current flown an ac circuit?
We have suppose the current flow in opposite to the direction of flow of electron.AnswerA.C. current reverses direction every half-cycle.
In induction motor the will the direction of the rotor will be in the direction of the current?
The direction an induction motor will turn depends upon the direction of the rotating field setup by the winding. Remember in AC the direction of the current reverses itself 120 times every second for a 60 hz system. So no it will not turn in the "direction" of the current.
Are Household appliances AC or DC?
kettles generally run on alternating current (AC) as do most household appliances. although the heating element can run on either alternating or direct current (ac or dc) as long as the voltage is the same. for example if you were to plug your kettle into your car battery it wouldn't do very much if anything. however if you were to wire ten car batteries in series ( thus creating 120 volts dc) the kettle would heat up as it normally would.
What component of a motor changes the induced AC voltage into a pulsating DC?
The commutator is the moving part of the electrical switch in motors that reverses the current direction between the rotor and the external circuit. This is applicable in electrical motors and electrical generators.
How does a Diac work?
A DIAC operated with a DC voltage across it behaves exactly the same as a Shockley diode. With AC, however, the behavior is different from what one might expect. Because alternating current repeatedly reverses direction, DIACs will not stay latched longer than one-half cycle. If a DIAC becomes latched, it will continue to conduct current only as long as there is voltage available to push enough current in that direction. When the AC polarity reverses, as it must twice per cycle, the DIAC will drop out due to insufficient current, necessitating another breakover before it conducts again
When current in a circuit reverses its direction in a regular pattern it is called?
An "Alternating Current" (AC).
What is the name of the current which reverses direction every half turn?
AC (alternating current).
Current that reverses direction in the regular pattern is called?
This is known as a direct current or DC. The two major types of currents are AC (alternating current) and DC (direct current). In AC the charges move back and forth, but in DC the charges flow in JUST ONE DIRECTION. Due to this characteristic it will not reverse direction like AC can.
What direction does current flown an ac circuit?
We have suppose the current flow in opposite to the direction of flow of electron.AnswerA.C. current reverses direction every half-cycle.
Why select dc appliances oven ac powered appliances when using solar generated power?
this is because ac appliances need regular reversal in magnitude and direction whereas dc need a regular supply.. so no output will be produced when using ac.. that's why we use dc appliances!!!!
What does the retifier on gators do?
Assuming you mean "rectifier", a rectifier is an electrical device that converts AC, which periodically reverses direction, to DC, which flows in only one direction.
What is AC current?
An AC current (alternating current) is one that changes its direction continuously - typically at 50 or 60 Hertz (cycles per second).
What is the purpose of a rectifier?
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction.
When flow can reverse its direction regularly it is called?
Alternating Current (AC) reverses its flow constantly, unlike DC (constant current) which flows in one direction only.
At what voltage does the appliances work in America?
120 V or 240 V AC
What is the definition of AC generator?
An electric device that produces an electric current that reverses direction many times per second. Also called a synchronous generator.
Why do you still use both ac and DC?
Because some appliances work with ac current and some with dc current.
