WebbOhm’s law shows a simple relation between these three quantities. Ohm’s law states that the current through a conductor between two points is directly proportional to the … WebbAs the potential difference (voltage) across a component is increased, the current also increases (by Ohm’s law) \t; The precise relationship between voltage and current is different for different components and can be shown on an I–V graph \t; For an ohmic conductor eg. a fixed resistor: \t; The I–V graph is a straight line through the ...
