A light bulb is rated at 50.0 W when operated at 120 V. The filament in the light bulb has a cylindrical shape with diameter 0.60 mm. How much charge per unit area enters (and leaves) the light bulb in 30.0 seconds? Hint: Find the charge passing through the bulb in 30.0 s seconds and divide that by the cross-sectional area of the filament
