In direct current the voltage and current remain the same at all times. Direct current is more efficient when traveling longer distances, but has a higher loss rate when distributing to many people and its much harder to change the voltage.

What has the author Erich Uhlmann written?
Erich Uhlmann has written: 'Power transmission by direct current' -- subject(s): Direct current, Electric power distribution
What are the merits and demerits of machine language?
Merits: Machine language allows for direct communication with the computer hardware, resulting in very fast and efficient execution of instructions. It is also not dependent on any translator programs for execution. Demerits: Writing programs directly in machine language is very complex and error-prone, making it difficult for programmers to work with. It is also platform-dependent, meaning programs may need to be rewritten for different hardware architectures.
Which current flows in one direction only?
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.
What are the merits of direct finance?
k.;k
What is DCDB in batteries?
DCDB: Direct Current Distribution Board. It use for Battery Charger..etc. There is also a ACDB.
Will a battery supply direct current or alternating current or ac?
direct current.
How many types of direct current and what is the frequency of direct current?
There is only one type of direct current and its 'frequency' is zero.
Which would make more shock the alternating current or direct current?
direct current
Is your house alternating or direct current?
Alternating current. Direct current is used in batteries.
What is DC power?
Direct current (DC or "continuous current") is the unidirectional flow of electric charge. Direct current is produced by such sources as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type. Direct current may flow in a conductor such as a wire, but can also be through semiconductors, insulators, or even through a vacuum as in electron or ion beams. In direct current, the electric charges flow in the same direction, distinguishing it from alternating current (AC). A term formerly used for direct current was Galvanic current. Direct current may be obtained from an alternating current supply by use of a current-switching arrangement called a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be made into alternating current with an inverter or a motor-generator set. The first commercial electric power transmission (developed by Thomas Edison in the late nineteenth century) used direct current. Because of the advantage of alternating current over direct current in transforming and transmission, electric power distribution today is nearly all alternating current. For applications requiring direct current, such as third rail power systems, alternating current is distributed to a substation, which utilizes a rectifier to convert the power to direct current. See War of Currents. Direct current is used to charge batteries, and in nearly all electronic systems as the power supply. Very large quantities of direct-current power are used in production of aluminum and other electrochemical processes. Direct current is used for some railway propulsion, especially in urban areas. High voltage direct current is used to transmit large amounts of power from remote generation sites or to interconnect alternating current power grids.
Which is better for transmission alternating current and direct current?
Alternating current is better than direct current for transmission.
What is DC in electric stand for?
Volts direct current eg battery As opossd to Vac wich is volts altinating current eg mains supply
