When a capacitor is fully charged, the current through the capacitor in a direct-current circuit is
a. zero.
b. at its maximum value. c. equal to the current in a resistive circuit in parallel with the capacitor circuit.
d. greater than the current in a resistor that is farther from the battery than the capacitor.
e. zero if it is the only capacitor, but maximum if there is another capacitor in series with it.
