A parallel combination of an 10 Ω resistor and an unknown resistor R is connected in series with a 12 Ω resistor and a battery. This circuit is then disassembled and the three resistors are then connected in series with each other and the same battery. In both arrangements, the current through the 10 Ω resistor is the same. What is the unknown resistance R?
