A battery delivers a source of direct current.
direct current.
A battery provides direct current (DC).
Direct current, as opposed to alternating current.
dc in battery stands for direct current .ac is alternating current.
directA dry cell battery produces DC.
Light bulb in the home - alternating current (A/C) Light bulb in a car - direct current (D/C) Output of a battery charger - direct current Input of a battery charger - usually alternating current
Alternating current. Direct current is used in batteries.
When you plug something into the wall socket at home, (mains power) you are using alternating current, when you use something powered by a battery, you are using direct current.
Alternating current is better than direct current for transmission.
A car alternator generates alternating current, then uses a rectifier to convert the alternating current to direct current, it charges your battery and supplies the current to run all the electrical systems in the car.
An AC Adapter converts direct current into alternating current. It is handy when you only have 12 volt battery current and you need to use power tools which only run on alternating current.
The question is much too vague. Electronic devices can be designed to allow for direct or alternating current. Examples are your home DVD player plugged into the receptacle which is 120 volt alternating current and your ipod which uses battery direct current power. Small portable devices are usually direct current (battery power ). The plug that comes with such devices is for charging the battery. Or the device may internally rectify the alternating current and turn it into dc power.
