Two identical ideal diodes are connected to an ammeter and a d.c source (1 volt) as shown. In which one of the following circuits, ammeter will not show any defection?
(d)
(a)
(b)
(c)
Solution
In circuit (a) the two diodes are in series and one of the diodes is reverse biased. Hence no current will flow in the circuit and ammeter will not show any deflection.
