For example: you can plug in a 15 watt light bulb into a 20 amp circuit. The light bulb uses what it needs, If your fears were correct, the light bulb would explode the moment the current was turned on, because the 20 amps available is WAYYYYY more that the light bulb needs. Since that doesn't happen, your fears are also not going to come true.
(everyone is free to trash my analogy... however, it is a decent one for a electrical layperson)
The one exception would be a drunken partygoer turning the volume up to 100% on a heavy metal song.. this is a different problem than the one you seem concerned about.
