What is the resistance of a light bulb if a potential difference of 120 V will produce a current of 0.5 A in the bulb? What is the resistance of a light bulb if a potential difference of 120 V will produce a current of 0.5 A in the bulb? 240Ω When the resistance in a circuit remains constant how are the voltage and current related? The current doubles when the voltage doubles because they are directly proportional. what is the resistance of a light bulb if a potential difference of 120 v will produce a current of 0.5 a in the bulb? 0.0042 0.5 60 240. 2. Voltage is directly proportional to current because I = V/R What is the resistance of a light bulb if a potential difference of 120 V will produce a current of 0.5 A … What is the resistance of a lightbulb using Ohm's law Resistance of a light bulb - Home | Boston University Physics Resistance of a light bulb - Home | Boston University Physics Resistance of a light bulb - Boston University Physics Thu Oct 24 2019 · Given that Potential difference of a light bulb V = 120 V. Current produced in the light bulb I = 0.5 A. We need to find the resistance of the light bulb. It can be calculated using Ohm's law. It is given by : V = IR. R = 240 ohms. So the resistance of alight bulb is 240 ohms . When they are placed in series the total resistance is about 500 W so each b...
