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.
A device called an inverter is used to convert direct current (DC) to alternating current (AC). The inverter switches the direction of the current flow at a rapid rate, creating an alternating current output from the direct current input.
Alternating Current which reverses its direction regularly at certain intervals Direct Current flowing continuously in one direction only
Alternating current is better than direct current for transmitting electricity over long distances because it can be easily converted to higher or lower voltages using transformers, which reduces energy loss during transmission. Additionally, alternating current can travel longer distances with less power loss compared to direct current.
Alternating current is more effective for long-distance travel than direct current because it can be easily converted to higher voltages, which reduces energy loss during transmission over long distances. This is due to the ability of alternating current to use transformers to increase voltage and decrease current, resulting in lower energy losses compared to direct current.
Direct current (DC) this is produced by for example batteries. AC alternating current changes direction on a cyclical basis and is used in power distribution and what "comes out" of the power sockets in the home.
Alternating current. Direct current is used in batteries.
Alternating current is better than direct current for transmission.
Power lines carry electricity as alternating current.
To convert direct current to alternating current you need either an inverter or a motor-generator set.
