Shown in figure is a Post Office box. In order to calculate the value of external resistance, it should be connected between

In the following circuits, heat produced in the resistor or combination of resistors connected to a 12 V battery will be

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?
