WebApr 12, 2024 · A light bulb is non-ohmic because it does not obey Ohm’s law. According to Ohm’s law, “The ratio of potential difference to the current flowing through a conductor is constant, providing all other influences such as temperature are kept constant.” When a material is ohmic, the resistance remains constant when the temperature is kept constant. Weband R is the resistance of the resistor. The unit for resistance is the Ohm, abbreviated with the Greek omega, (1 = 1 V/A). Carbon resistors typically range from about 10 to about 10 …

WebNov 5, 2024 · Ohm’s Law Relationship Current And Voltage Remember; voltage is like pressure. It’s the pushing force in the circuit. It pushes the electrons around the wires and we place things like lamps in the way of the electrons so they have to flow through it and this causes the lamp to light up.
