WebAug 29, 2024 · Yes, a lightbulb does follow Ohm’s law. For a lightbulb to work, it needs a certain amount of current (measured in amps) to flow through it. The resistance of the lightbulb determines how much current will flow. If the lightbulb has a high resistance, then less current will flow; if the lightbulb has a low resistance, then more current will flow. WebThe light bulb does obey Ohm’s law because the graph of Voltage vs. Current shows a linear relationship with the slope corresponding to resistance. At high voltages, the slope of the line became constant. At intermediate voltages, the slope followed a linear relationship; as voltage increases, current increases at a constant slope, R. ...

WebJun 28, 2024 · Ohm's Law simply states that for a given resistor, the current and the voltage are directly proportional. So if you increase the voltage by 10%, the current goes up by 10%. If you halve the voltage, the current is halved. This matches up quite well with the old water-in-a-pipe analogy that you often hear about when discussing electricity.
