Finding potential difference across resistors
http://physics.bu.edu/~duffy/sc526_notes05/notes08_circuits.html WebSep 20, 2015 · In the above circuit, the potential difference across each resistor can be calculated using Ohm’s Law. The series circuit has a current of 1 A flowing. Then according to Ohm’s law. Potential difference across the resistor R1 is I × R 1 = 1 × 1 = 1 V. Potential difference across the resistor R2 is I × R 2 = 1 × 2 = 2 V.
