Name a physical quantity which has same unit as of work?

A parallel combination of an 8 Omega resistor and an unknown resistor R is connected in series with a 16 Omega resistor and a battery. This circuit is then disassembled, and the three resistors are then connected in series with each other oand the same battery. in both arrangements, the current through the 8 Omega resistor is the same. What is the unknown resistance R?
