Can light bulbs be ohmic
WebA light bulb is a common example of a non-ohmic conductor. Other examples of non-ohmic conductors are diodes and transistors. In a light bulb, the resistance of the filament wire will increase dramatically as it warms from room temperature to operating temperature. If we increase the supply voltage in a real lamp circuit, the resulting increase ... WebThe light bulb is non-ohmic because of its high temperature burning.
