What is direct current and alternating current?

Answer 1

Direct current is a constant, steady state current, such as obtained from a battery. Alternating current is constantly switching polarity, usually in a sinusoidal waveform, such as obtained from an alternator, a form of generator that does not have a commutator.
Direct Current and Alternating Current:

The first and simpler type of electricity is called direct current, abbreviated "DC". This is the type of electricity that is produced by batteries, static, and lightning. A voltage is created, and possibly stored, until a circuit is completed. When it is, the current flows directly, in one direction. In the circuit, the current flows at a specific, constant voltage (this is oversimplified somewhat but good enough for our needs.)

The other type of electricity is called alternating current, or "AC". This is the electricity that you get from your house's wall and that you use to power most of your electrical appliances. Alternating current is harder to explain than direct current. The electricity is not provided as a single, constant voltage, but rather as a sinusoidal (sine) wave that over time starts at zero, increases to a maximum value, then decreases to a minimum value, and repeats.

Answer 2

An open circuit which as you see i am not making sence but this will not be shown i will add that this question can be answered with some notes you should have and should not be asking other people it have a good day

Answer 3

In Spanish, a direct current is called "corriente continua" - continuous current. A direct (or continuous) current flows continuously in a single direction.

An alternating current changes direction all the time.

Answer 4

Yes battery deliver a direct current not a alternating current because battery has

limited amount of energy and to create a electric pressure acrross the circuit it gives out a direct current. Therefore alternating current varie from 0v - 240v and it keeps on varying.

Answer 6

Its DC but needs to be hooked up to an inverter to convert it into AC before you can use it.

Answer 7

All electricity that is brought to your home is Alternating current

Answer 8

A car is run on dc (direct) current
