Ohm's law is not wrong. Here's what the problem was, in the first problem
where cap dissiption was really large and scary, P=I^2 R was used. In order
to get a 10x current increase on a fixed resistor (ESR of the caps) you
need a 10X increase in voltage. 10X voltage times 10X current = 100x the
power. In our case, the voltage was fixed, and never went up 10 times.
Somewhere some math about RMS current is off like you said.
