Dc or direct current is and electrical current flowing in only one direction. Examples would be batteries or solar cells. ac or alternating current is current flowing or "alternating" in more than one direction. An example is the outlet you plug a cord into to power devices or appliances in your home or businesses. rectification of these is simply the conversion of one to the other, because sometimes the device your trying to power needs one type of current and the only available type current is the other. So in essence you have to convert or "rectify" one power source into one usable for your purposes. An example of this is a laptop. A laptop or any other type of mobile computer uses a battery for power, which is direct current. In order to keep your laptop battery charged you must plug in the ac adapter in a wall socket near by. The problem is your laptop uses direct current and what you are about plug your adapter into to power or charge your mobile computer is going to be alternating current. The two are not interchangeable. The solution lies with the actual ac adapter itself. If you'll notice there is a small to medium size box in the middle of the cord. The box is designed to convert, or "rectify" the type of current going from the wall to your mobile computer from ac to dc power.

What is the difference between alternators and dynamos?
Alternators produce AC, which is rectified by diodes if DC is needed. Dynamos produce DC by using a commutator.
What is the difference between ac and dc grounding?
The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
What is the difference between in ac and dc powwer cable?
There is no difference in the cables. The only difference is the type of electrical power being transmitted. AC or DC applications use the same wires.
What is the difference between a voltage converter and a voltage inverter?
Converter is AC to DC. Inverter is DC to AC
Why used ac over dc in train?
ac transmits the voltage over long distances. so v use ac in trains
What is the difference between alternators and dynamos?
Alternators produce AC, which is rectified by diodes if DC is needed. Dynamos produce DC by using a commutator.
What is the difference between AC and DC choke?
There is no difference between AC AND DC chockes
What is an ac voltmeter?
A: It is a regular DC voltmeter but the AC is rectified and the DC component is measured and displayed as AC VOLTS.
What is the difference between ac and dc grounding?
The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
What is the difference between in ac and dc powwer cable?
There is no difference in the cables. The only difference is the type of electrical power being transmitted. AC or DC applications use the same wires.
What the difference between AC and DC?
AC rises with respect to time but DC is steady.
What is the difference between rectifier and converter?
A rectifier converts AC voltage into DC voltage. A converter is something more general. It describes not only rectifiers, but also devices that can turn DC into AC or perform DC-to-DC or AC-to-AC conversion.
Difference between magneto and ac generator?
magneto is dc
What is main difference between ac power and dc power?
AC power is made by alternating current and DC does not change.
What is the difference between ac ammeter and dc ammeter?
dc ammeter has three connecting pins while ac has four
How do you calculate the ac amps when you have the DC volts DC amps and the ac volts?
the answer is dc volts are rectified from ac volts and the amperage will be the same unless you account for the slight drop from the rectifier. dc volts from a battery have no relationship to ac volts. you can derive ac volts from a dc source using an inverter.
What is the difference between current (DC) and alternating current (AC)?
ac comes directly from the power socket, and DC is battery source. Answer2: The frequency is the difference, AC has frequency f>0 and DC does not f=0.
