Obviously you have not yet begun the AC circuit analysis class. Wait a few quarters.
Some components are normally used with DC, some components are normally used with AC, but most components can be used with both DC and AC.
Electronics devices are work both AC and DC currnt . Such as Diode , SCR , Capacitor can work both AC and DC current . Espacilly voltage control circuits such as dimmer , and then voltage rectifier circuits , means power suppy circuts and so on.
DC direct current is be coming more popular than AC alternating current AC is not really suitable for some devices maybe your device is needing low current
Almost all digital electronics use a AC to DC power supply. Digital electronics cannot handle AC. all electronics device having battery powered are using DC power supply http://www.wzmicro.com
A device called a power inverter.In old vacuum tube radios an electromechanical device called a vibrator was used.Another device is a motor-generator using a DC motor and an AC generator.
A device which requires 1000mA at 9 volts in order to operate will not work from an output of 500mA. This output is only half the power requirement of the device.
The Siemens DC drive is a masterdrive which is utilized on an Integrated Device Electronics Chain. The DC drive works by suppling AC and DC power to the drive.
As in all electronics devices that obtain power from the AC electric system, a power supply converts the AC to the DC voltage(s) needed by the electronics in the device. Depending on the needs of the device this power supply may deliver a single DC voltage or as many as several dozen different DC voltages.
All the cell phones are working in DC only
Yes, the device will only use whatever amps it needs.
dc to dc converter
Depends. Lamps can certainly be built to work on either AC, or DC, or both. But some lamps, particularly those with electronics in them, either a dimmable lamp, or a fluorescent lamp, may only work with one type of electricity.
first, understand that a transformer is an AC DEVICE. it wont work on dc...
