    Just my 2 cents worth--I ahve found a way to explain this that is usually easier for people to follow---

    You only need 100hp in your car to do what it needs to but you have a 500 hp engine--everything works fine and you only use 100 hp but you have 500 available--same with electricity--you need 5 amps but have a 20 amp circuit(engine)--you will only use 5 amps but you have 20 available

    And the analogy carries through that if you will never use more than 100 HP you may have paid more than you needed to for the engine.
    But if that was the only engine option available then tbere
    is no point in getting a custom 100 HP engine designed and built
