In my physics class, we did an experiment in which we supported Ohm's law. We used a simple circuit that includes one resistor. The relationship of I = VR, and variants thereof, became apparent. We mainly looked at the relationship between potential difference and the current in series.
What we have not done is see if this relationship is apparent in a series circuit with multiple resistors. I've did further research and read about Non-ohmic resistors, do they have anything to do with this? I can't really make the connection.
So my question is, what is the relationship between the potential difference across two resistors in series and the current through them? We are moving towards parallel, but I would like to know this question better.
