Consider a box with three terminals on top of it as shown in figure.

Three components namely, two germanium diodes and one resistor are connected across these three terminals in some arrangement.

A student performs an experiment in which any two of these three terminals are connected in the circuit shown in figure.

The student obtains graphs of current-voltage characteristics for unknown combination of components between the two terminals connected in the circuit. The graphs are,

(i) when A is positive and B is negative

(ii) when A is negative and B is positive

(iii) when B is negative and C is positive

(iv) when B is positive and C is negative

(v) when A is positive and C is negative

(vi) when A is negative and C is positive

From these graphs of current-voltage characteristic shown in fig. (c) to (h), determine the arrangement of components between A, B and C.
