A 20-ohm resistance is connected in parallel with a 60-ohm resistance. Another set, 80-ohmandanunknown resistor are also connected in parallel. The two sets are connected in series. If thesupplyvoltage is 120 V , find the ohmic value of the unknown resistance so the voltage across thefirst setis twice as much that of the second set.
