The main problem I see is that a large section of the population would probably starve/die before they figured out what was wrong.
Essentially if I understand the premise, no electricity in any form works, so there would be no communications and essentially every device we have would no longer work. So, if you were to wake up today and find out that had happened, what would you think had happened? An EMP? Are we at war? A terrorist act? There would be no way short of a wave of bike messengers to travel everywhere to investigate and find out that it happened everywhere. Most people would probably stay put to guard their houses and possessions, waiting on help to arrive. After all the military must be working to fight the enemy and eventually rescue would come.
Essentially everyone would exhaust local food supplies. No one would be thinking to have to abandon everything and get out to the countryside and start farming before it is too late. Even then how many have horses and plows? A modern farmer would be helpless also, who has a horse? They might have an old family plow out in the barn rusted from 100 years ago if they were lucky. Even then they might get overrun by starving hordes from nearby cities.
I could see decimation of the population. People would not even realize there was a real problem until it was too late to even try to do anything about it.
