The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω): The voltage V in volts (V) is equal to the power P in watts (W) …
WebLet's say you have a 120-watt light bulb plugged into a wall socket. The voltage is 120 volts, and a 120-watt bulb has 1 amp flowing through it. You can calculate the resistance of the filament by rearranging the equation: R = V/I So the resistance is 120 ohms. Web1 dec. 2024 · (A typical bulb has a resistance of 7 to 8 ohms through the filament and 2 to 3 ohms through the shunt once the coating burns off.) Several series or groups of lights can be wired to just one plug. This is known as being wired in parallel. Although you can buy simple 50-bulb strands, it is more common to see 100- or 150-bulb strands.
