In my calc based physics class, we are studying circuits and I talked about batteries and capacitors.
I explained that a capacitor stored electrical energy..yadda yadda
One of my students then asked me what the difference between a capacitor and a battery is. I was like a capacitor stores energy, and a battery is a voltage source.
He then asked me why you would need a capacitor in the first place, why not just use batteries. I was like you need to store charge for somethings and a battery can't do that.
It seems there is a piece in here that is important. He thinks something about the battery and the capacitor is the same and I am at a loss to explain what that could not be or how to explain the differences better.
My guess is that he thinks that a battery has charge and holds the charge...
