Two uniform conducting strips, P P\,P and QQQ, are made from the same material and maintained at the same temperature. They are connected in series across a battery. The strips have different values of L/AL/AL/A, where L L\,L is the length and A A\,A is the cross-sectional area.
Which two quantities are the same for P P\,P and QQQ?
resistivity and resistance
potential difference across each strip and current
current and resistivity
resistance and potential difference across each strip
