In 1887 direct current (DC) was king. At that time there were 121 Edison power stations scattered across the United States delivering DC electricity to its customers. But DC had a great limitation -- namely, that power plants could only send DC electricity about a mile before the electricity began to lose power. So when George Westinghouse introduced his system based on high-voltage alternating current (AC), which could carry electricity hundreds of miles with little loss of power, people naturally took notice. A "battle of the currents" ensued. In the end, Westinghouse's AC prevailed.But this special feature isn't about the two electrical systems and how they worked. Rather, it's a simple explanation that shows the difference between AC and DC.

AC...'s full form is Alternate Current. can be transmitted to long distances. is generally of 220 Volts or more... don't have +ve and -ve ions... is generated by AC generators which work on diesel etc.

...DC stands for direct current.. can't be transmitted to long distances. is of 12 Volts. do have positive-negative ions. is generated by DC generators..
