WebA resistor’s resistance is defined as the ratio of potential difference V to current I. Ohm’s law is confirmed using the graph between V and I, as the plot is a straight line. A circuit’s … WebThis is the current passing through each resistor. The potential difference across each resistor can by found using Ohm's Law: Each 8 W resistor has a potential difference DV = I R = 4 V . The 4 W resistor has a potential difference DV = I R = 2 V . The sum of the potential differences across each resistor equals the battery voltage, as it should.
WebV-I graph is a straight line passing through the origin of the graph as shown. Conclusion : Straight line nature of graph shows that the current is proportional to the potential difference. Hence, Ohm’s law verified. The slope of V-I graph gives the value of resistance of the conductor at the given temperature.
