How does a device convert direct current (DC) to alternating current (AC)?
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.
Direct electric current cannot be used to operate A. Electric motors B. Electric heaters C. Electromagnets D. Transformers?
Direct electric current cannot be used to operate D. Transformers.
Name device which permits direct current and opposes the flow of alternating current?
A device that permits direct current (DC) and opposes the flow of alternating current (AC) is a rectifier. Rectifiers are electronic components that only allow current to flow in one direction, which is common for converting AC to DC in power supplies and other applications.
Why are steam turbines unable to produce direct current?
Steam turbines cannot directly produce direct current (DC) because they inherently generate alternating current (AC) due to the rotating motion of the turbine blades. To convert this AC output to DC, a device called a rectifier is needed. Rectifiers use diodes to change the flow of current, converting the AC produced by the steam turbine into DC suitable for most applications.
Does a fluorescent ballast work in a DC V supply?
No, fluorescent ballasts are designed to work with AC voltage supplies. They require the alternating current to function properly and cannot operate on a direct current (DC) power source.
What changes alternating current into direct current?
Yes but is somewhat complicated to get good level DC from an AC source.================================Answer #1.5 :All electronic devices operate on DC ... radios, TVs, computers, stereos, etc.If the device plugs into the wall outlet for power to operate, then the AC fromthe wall outlet is used to produce DC internally to run the device.
Did ceiling fan operate on dc or ac current?
ac current
What is AC motor and DC motor?
AC stands for alternating current, and DC is direct current. A motor is a device that uses electrical energy to spin. An AC motor uses AC voltage, and a DC motor uses DC voltage. http://ezinearticles.com/?The-Difference-Between-AC-and-DC-Electric-Motors&id=193767
How do you make Alternate current in vehicles?
You buy an inverter that takes 12 VDC as input. Just size the unit such that it can provide the current you need to operate the AC device.
What kind of electric current does an electric stove use?
An electric stove uses Alternating Current to operate.
Which is the device that converts AC to DC?
A Rectifier converts Alternating current into Direct current
What kind of electricity does America use?
America uses 60 Hertz (Hz) Alternating Current (AC). Most smaller devices operate on 120 volt current.
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
Main difference between ac and dc motor?
Dc is an electrical term for direct current. Ac stands for alternating current. As you probably guessed a dc moter uses dc current and an ac moter uses ac current. P.S. Most home outlets use ac current.
What devices typically use DC current to operate?
cell phones, laptops, desktops, anything that uses a battery. most power supplies convert AC to DC at a regulated voltage and current.
What are the roles of a diode and a capacitor in an AC-DC converter?
An AC-DC converter you can operate a device on AC instead of batteries. ~bobbyjack~ : D
Do cars use AC or DC current?
Most automotive applications use DC, although the alternator is an AC device which uses a rectifier to produce DC. http://en.wikipedia.org/wiki/Direct_current
