I was reading about resistance and it said that resistors are used to limit the current in a circuit. How does a resistor reduce the current in a series circuit? They lose energy therefore they move slower? Or does it simply prevent electron flow?
In addition to that, how does adding more batteries in a series circuit increase the current? Well, I mean: In the example there is a series circuit with an ammeter, and a resistor with a voltmeter connected to measure the potential difference across the resistor or across the battery I can't remember, but there was just one resistor anyway. The resistor was the same: Whenever batteries were added, the potential difference increased and the current increased. I am guessing the current was still the "same" but with more energy (voltage) a greater current was able to be pushed through the resistor.
