How much current (amps) is drawn by a 80W light bulb plugged into an electric outlet (electric potential = 120v)
A light bulb is connected to an electrical outlet. a. How much current (amps) is drawn by a 80W light bulb plugged into an electric outlet (electric potential = 120v)? b. What is the resistance of the light bulb?
4. Consider a 60W light bulb plugged into a 120V socket, and a 100W light bulb plugged into another 120V socket Recall that a bulb's brightness is related to the amount of power (in watts) that is dissipated as heat and light. a Through which light bulb is more current passing? b. Which light bulb filament has more resistance? c. If these light bulbs were connected together in series into the same 120V outlet, which light bulb will be brighter?...
