Hey guys! Novice physics scholar here who's studying electronics on his downtime. I have some questions concerning AC and DC. If you guys could answer them (simplistically please, I still have a lot to learn :P) I'd really appreciate it.
I'm reading here that 'AC costs less to generate then DC'. Why is that? If anything, I'd think that DC would be cheaper and easier to use. After all, wouldn't it require MORE energy to constantly alternate the direction of a current, as opposed to simply letting a current run a direct course, as it does in DC?
Now, new question... AC current DOES typically generate MORE energy then DC, right? Since the direction of current is constantly being mixed up, the SAME electrons end up traveling a FARTHER distance. Whereas in DC, because the direction of current is so linear, it would seem as if the electrons reach the opposite battery terminal far more quickly then they would in AC, thus lending a shorter 'current life' to DC then to AC. In other words, if you have a 10 V AC battery and a 10 V DC battery, the AC battery would last far longer then the DC.
Am I correct here? Or am I just not making any sense at all?
