correct, but I don't know how large these are typically, an anecdote: I visited a friend who had a lamp socket (with shade) above his desk, and he was complaining about the fluorescent bulb he put in, in comparison with the resistive filament bulbs he usually put in: it was ticking even though the switch in the wall was turned off. At first I suspected a bad contact, but that didn't really make sense. Then I realized what was probably happening: capacitive leakage, so I ask if the socket has 2 switches? sure enough. the distance between the switches was long enough so that the parallel wires embedded in the wall effectively formed a long capacitor, so in both of the off states AC current was flowing through this unintentional capacitor. AC will also have inductive losses yes.
