Webcomponent, one can determine whether the ratio DV/I is a constant or not. If it is constant, then the component is ohmic and the constant resistance in ohms can be determined. If the voltage to current ratio is not constant, the device is not ohmic and does not obey Ohm’s law. A voltmeter is used to WebOne way to make such a bulb is to have a single filament, but place the voltage across different parts of it, depending on which brightness is desired. Again, Ohm's law plays a role in determining the fraction of the filament that the the voltage is placed across, and the resistance of the entire filament.
