Answer to Question #2419 in Electric Circuits for Jake
The voltage adapter of a cell phone charger reduces the wall outlet voltage to 5.2 and 1.0 Amps. how much charge passes through the cell phone while it charges for forty minutes?
The voltage adapter converts the voltage, but not the current. You can find the charge passed thrugh the cell phone by the following formula: Q = It, where I& is the current and t is the time.
