motor speed control.used in battery backup systems
Alternating current is better than direct current for transmission.
Volts direct current eg battery As opossd to Vac wich is volts altinating current eg mains supply
Power lines carry electricity as alternating current.
Direct current, as opposed to alternating current.
These are used with low range ammeters to measure current in HVAC 's where direct connection of instruments is impratical. They not only insulate the instruments from HV lines but also step down current in a known ratio. ( i .e . ) Iline =(I1 \I2) * Ammeter Reading where Iline = Line Current I1 \I2 = Current Ratio
i want to know about the advantage and disadvantages
Throughout the world the system used for home electrification is alternating current (AC).
Mention advantage of direct rule
electrification is processes of charging in which neutral body is charged by removal or addition of electrons
direct current.
There is only one type of direct current and its 'frequency' is zero.
direct current
Alternating current. Direct current is used in batteries.

Caltrain electrification is expected to start in 2019
The Electrification of the Soviet Union was created in 1987.
Three types of electrification are overhead line electrification, third rail electrification, and diesel-electric electrification. Overhead line electrification uses wires suspended above the tracks to provide power to trains, third rail electrification uses a rail alongside or between the tracks to supply power, and diesel-electric electrification uses a combination of diesel engines and electric generators to power the train.
