What else can I help you with?
What supplies alternating current?
An alternator (a.c. generator).
What is the purpose of a alternator?
A car alternator generates alternating current, then uses a rectifier to convert the alternating current to direct current, it charges your battery and supplies the current to run all the electrical systems in the car.
Advantages and disadvantages of polyphase circuit?
fewer ripples in a direct current when alternating is converted to direct current
Advantages of Ac to DC converter?
some things requre a dc (direct current) rather than an ac (alternating current)
What is special about AC power supplies?
AC power supplies are power supplies that use Alternating Current, which means that the current repeatedly changes its direction. AC power supplies are usually mains supplies as they are at a high voltage. Often filtering takes place between the mains supply and the device.
What is one way that alternating current is more useful than direct current-?
alternating current is easier to transfer long distances
What is AC power plug?
an AC power plug is one that utilizes AC (or alternating current) to power a device. Alternating current is different to direct current (or DC) in the way that instead of providing a direct source of power, it alternates between negative and positive. Most devices rely on Alternating current due to circuitry reasons
What is alternating current machine?
"What is alternating current machine?"
What is a graphical representation of alternating current?
The symbol for alternating current is: ~
Does vac stand for volt amp current or volt alternating current?
Vac usually stands for voltage alternating current. It represents the voltage of an alternating current electrical system.
Name device which permits direct current and opposes the flow of alternating current?
A device that permits direct current (DC) and opposes the flow of alternating current (AC) is a rectifier. Rectifiers are electronic components that only allow current to flow in one direction, which is common for converting AC to DC in power supplies and other applications.
Is your house alternating or direct current?
Alternating current. Direct current is used in batteries.
