Hello All,

I have some basic questions,in which I lack concepts....

1. What is meant by a Potential Difference...........Is Potential Difference = Potential
Drop ??

Also, water flows form a height to lower heights........Smlrly, Electric Current flows from a higher potential region to lower potential region........but what makes them flow so ???.................

2. Basically, what is the difference between an AC Current and a DC Current ?

Thanks.
