Why does it sometimes seem instant and sometimes it seems to take time for something to work? For example, if I leave my hoover switched on and plug it in, it seems to start immediately, but when I switch the plug off for my tv the stand by light takes a few seconds to go off?
Edit: thanks for the explanation guys, seems like the answer I was looking for was some appliances use capacitors.

Source google: This makes the observable speed of electricity about the same as the speed of light: 186,000 miles per second, or 299,792 km/s. With this known a simple calculation gives the speed of electrical activity through a wire stretching around the entire Earth at well under one second, about 0.134 seconds.
