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.
In: Physics
electrons actually move very slow. But they sort of ‘bump into each other’ and push electrons to the device. This is called drift velocity. Electromagnetic waves move at the speed of light. The electricity you’re referring to is the ‘signal velocity’ and is faster than drift, but slower than speed of light
