Five resistors are connected purely in parallel to a battery of
24 volts. Three of these resistors are equal and the current
through each is I. The current through the fourth resistor is 3.6
times larger than I, and the current through the fifth resistor is
4.7 times smaller than I. What is the power dissipated, in Watts,
of the fifth resistor if the equivalent resistance of all five
resistors is 13 Ohms?
