Q14.38Multiple choice
Consider a box with three terminals on top of it as shown in Fig.14.18 (a): Fig. 14.18 (a) 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 Fig. 14.18 (b). + – Box Terminals Fig. 14.18 (b) The student obtains graphs of current-voltage characteristics for unknown combination of components between the two terminals connected in the circuit. The graphs are
