Webband parallel, and to measure the current-voltage characteristics of a light bulb. Lab Preparation For many conductors, especially metals, the current flowing through a device is proportional to the voltage difference applied to the device: the ratio of the voltage to the current is a constant. This is Ohm's law. This ratio for a particular ... Webb16 feb. 2024 · Question 13. One of the fundamental equations used in electricity and electronics is Ohm’s Law: the relationship between voltage (E or V, measured in units of volts ), current (I, measured in units of amperes ), and resistance (R, measured in units of ohms ): E = I R I = E R R = E I E = I R I = E R R = E I. Where, E = Voltage in units of ...

If that resistance stayed the same with 120 V applied, Ohm's Law tells us that the bulb would draw about 12.5 amps and dissipate about 1,500 watts. That doesn't happen of course, and that's because as the filament heats up, its resistance increases as well.
