Chapter Problems Electric Current Classwork If 560 C of electric charge passed through a light bulb in 8 min; what was the magnitude of the average electric current passing through the bulb? If the current through a resister were 0.5 A; how much electric charge would flow through it in 2 min? How long would it take for 300 C of electric charge to pass through an aluminum wire if the current through it is 0.6 A? Homework What is the magnitude of the electric current passing through the heating coil of a hot plate if 25 C of charge passes through it in 8 s? An average current of 4 A flows through a pair of automotive headlights: how much electric charge flows through them in 5 h?
