Because of the chemicals and metals which are used to make it, a battery can only produce dc (direct current).

For the same reason a battery cannot produce ac (alternating current) on its own, but it can be connected to another device, which is called an invertor, to produce ac for use by devices which require ac instead of dc.

Many of the devices and other pieces of equipment to which a battery can be connected will only work on direct current (such as, for example, car starter motors) but some things (such as light bulbs) can work on either dc or ac.

Some batteries are rechargeable but they cannot be recharged using ac . That is why all battery chargers which are designed to plug into house ac power sockets must convert the ac to dc.

Which apparatus changes a direct current to alternating current?

An inverter is the apparatus that changes direct current (DC) to alternating current (AC). It does this by converting the fixed voltage and direction of DC electricity into an oscillating voltage and alternating direction of AC electricity.


Is alternating current a current type where electricity flows in the positive direction only?

No, alternating current (AC) is a type of current in which the flow of electric charge periodically reverses direction. It continuously changes magnitude and direction in a waveform pattern, unlike direct current (DC) which flows consistently in one direction.


Did Thomas Edison want direct current or alternating current?

Thomas Edison promoted direct current (DC) as the preferred method of electrical distribution. He believed DC was safer, cheaper, and more efficient than alternating current (AC) which was being championed by his rival, Nikola Tesla.


What is current direction?

Outside the battery, it is negative to positive and inside the battery it is positive to negative.


What are the 2 basic types of currents?

The main division is between alternating current (AC) and direct current (DC). AC is universal now for domestic and industrial supply, but DC used to be used in some places in the early part of last century. Automobiles use DC at 12V which is I think universal now. AC in domestic use can be at 50Hz (Europe and many other places) or 60Hz (North America), and can be at either 240V or 120V.

Current that changes directions is call direct current?

No, that's Alternating Current.

Compare alternating current with direct current?

Alternating current changes direction on a set frequency such as 50 Hz, 60 Hz or 400 Hz. Direct current always flows in one direction.


Is your house alternating or direct current?

Alternating current. Direct current is used in batteries.


What are the two kinds electricity?

Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction. In AC (alternating current), the current regularly changes its direction.Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction.

Which is better for transmission alternating current and direct current?

Alternating current is better than direct current for transmission.


Lightning carries Alternating current or Direct Current?

Power lines carry electricity as alternating current.


Which charging system component converts alternating current into direct current?

Diode rectifier


What is ac and what is DC?

DC stands for "direct current", AC for "alternating current". A direct current flows in a single direction; an alternating current changes its direction all the time, typicall 100 or 120 times a second (twice the frequency, which is measured in hertz).


What is an electric current that periodically changes direction?

An electric current that periodically changes direction is called an alternating current (AC). In AC circuits, the flow of electric charge reverses direction many times per second, typically at a frequency of either 50 or 60 Hz. This is in contrast to a direct current (DC) in which the flow of electric charge remains constant in one direction.


What converts direct current to alternating current?

To convert direct current to alternating current you need either an inverter or a motor-generator set.
