Can you use a 5v ac 550mA wall power supply in the place of a 5V dc1A car adapter?
No. If it is AC output, it will blow out the power circuits of the DC device. If it is DC output, it doesn't have enough current capacity for the load of the DC device. If you want to power a DC device with a wall wart, make sure the wart is: DC output Correct polarity (some have reversible polarity) Exact same voltage as the device Greater than or equal to current rating of the device
What type of device produces alternating current?
A "generator" usually produces DC current. An "alternator" usually produces AC current. Older cars up to the 1960's used generators. Newer cars use alternators (simpler design) with diode rectifiers to convert the AC to DC. Batteries are DC. Some electronic circuitry (inverters) can change DC to AC.
Asked in Car Batteries
Is car battery ac or DC volts?
Batteries by definition have to be DC. While u can convert DC to AC, with a device called an Inverter, none is built into a car battery. and chances are your car doesn't even have an Inverter anywhere in it. so car is DC. in addition modern cars use 12 volts, and for the record, AC and DC are not a "type of volt," they are types of current, (Direct Current, Alternating Current).

What device can be used to increase current in a DC circuit?
Asked in Cars & Vehicles
Which type of current we are using ac in automobiles?
The only type of current used by automobiles is dc current although the alternator produces ac current which is converted to dc by rectifiers built into the alternator. Even the alternator is controlled by dc current though through the use of a voltage regulator which limits the amount of negative dc sent to the stator and positive dc current sent to the rotor of the alternator which limits the EMF.
