equal to the power taken by the 4-ohm resistor. 2. A 20-ohm resistance is connected in parallel with a 60-ohm resistance. Another set, 80-ohm and an unknown resistor are also connected in parallel. The two sets are connected in series. If the supply voltage is 120 V, find the ohmic value of the unknown resistance so the voltage across the first set is twice as much that of the second set.
