A capacitor is a device having two electrodes that can be used to store electric charge. When a battery is attached to the capacitor, a positive charge moves to one electrode and an equal negative charge collects on the other. The capacitance of this system is defined as the ratio of the magnitude of the charge on either electrode to the voltage of the attached battery. Capacitance is measured in farads (coulombs per volt). A 1.5 volt D-cell battery is attached to a 2.2 picofarad capacitor. (a) Find the charge that appears on the positive electrode. (b) Find the charge that appears on the negative electrode. (c) Find the net charge of the entire capacitor.
