the aqa physics spec says we should be able to explain the differences. I cant find much on alternating pd, only on alternating current and direct current; are they the same thing? :/

The difference(s) between AC and DC is the same as the differences between alternating pd and direct pd.

When you think about it, if the p.d alternates, then the current should also be alternating (according to ohm's law).

So alternating p.d is the same as AC and direct p.d is the same as DC.
