You might be asking the wrong question. In North America, utilities deliver 120 volts AC at 60 hertz. This means the voltage at your electrical outlet rises to positive 60 volts and then goes to negative 60 volts. The 60 hertz means this happens 60 times a second.

If you mean you have an outlet with hot and ground or hot and neutral reversed, you should call an electrician. You can buy a cheap tester that will plug in to show you if you have a receptacle mis-wired this way. If the receptacle has a black and white wire connected, and the black wire is not the "hot" wire, it can be tricky to trace down the problem.
ac(Alternating Current ) has the high polarity.
maglev train works on alternating current..The electric current supplied to the coils in the guideway walls is constantly alternating to change the polarity of the magnetized coils. This change in polarity causes the magnetic field in front of the train to pull the vehicle forward, while the magnetic field behind the train adds more forward thrust.
When changing the auxilary face winding connection the current flow in the winding is changed so that the rotating emf direction is changed . Thats why the motor rotates in opposite direction.
AC stands for alternating current and means that the current changes directions, flipping repeatedly from positive to negative and back again.DC means direct current, the current only flows in one direction and does not change polarity.
yes
Yes!
The polarity of an electromagnet is determined by the direction of the electric current flowing through the wire coil. Reversing the direction of the current will change the polarity of the electromagnet.
ac(Alternating Current ) has the high polarity.
No. you cant change it's polarity because electrical current that a house uses is not a + - type, it changes it's polarity 50 times per second.
As we touch an ac supply in which due to body resistance , we create a phase difference between the ac supply and us . As ac reverses polarity , so do we , but our polarity change is opposite to that of the polarity change of ac supply , hence our body gets attracted to the ac supply .
The overall polarity of CO in the current market trends is positive.
Polarity in welding has to do with the direction of the current in the welding process. With direct current (DC) the welding circuit can either be straight, or reverse polarity. When the machine is set for straight polarity, the current flows from the electrode to the weld surface and creates considerable heat in the metal. When the machine is in reverse polarity, the current is backwards and is flowing from the metal to the electrode causing a grater concentration of heat at the electrode.
An alternating current (AC) is produced when a wire cuts through magnetic field lines and experiences a change in polarity. This phenomenon is known as electromagnetic induction, where the changing magnetic field induces a current in the wire.

This change in polarity causes the magnetic field in front of the train to pull the vehicle forward, while the magnetic field behind the train adds more forward thrust.
If you reverse the polarity in a parallel circuit, the components will still function but the direction of current flow through each component will be reversed. This could lead to a change in the behavior of any polarized components in the circuit, such as diodes or electrolytic capacitors. It is important to ensure that the components can handle the reversed polarity to prevent damage.
