I am beginning my study of electrical engineering and I apologize in advance if this question has been asked or if this question does not make any sense. I was wondering why short circuits are "bad" and complete circuits are "good".
From what I understand, when you have a battery, and short the two terminals together, you introduce a large current into the battery causing it to overheat and possibly combust.
However, when you add some form of resistance to the circuit, you create a complete circuit and the battery source is not in jeopardy of overheating.
My question is, is there not current flowing into the battery in a complete circuit? How come the battery is unable to handle the current under its own voltage? And if some form of resistance on the circuit is required in order to prevent a short circuit scenario, how much of a resistance do I need, in order to prevent the battery from overheating? Thanks in advance. Cheers.
