Answer

a). The third resistor has the largest current, since the total current through the other two resistors is equal to the current through the third. b). The third resistor also has the largest voltage, since the current through it is the largest and all the resistors have the same resistances value (V=IR). c). The third resistor has the largest power output, because it has both the largest current and largest voltage.
