Which circuit will not show current in ammeter ?A. Figure 1B. Figure 2

1.	Which circuit will not show current in ammeter ?A. Figure 1B. Figure 2C. Figure 3D. Figure 4
Answer» Correct Answer - A Current wilI flow in (2), (3) and (4) because in (2), the diodes are in series and are forward biased. In (3), they are m parallel but one is forward biased and the other is reversed biased. Hence no current will flow in that diode but the current flows through the other diode. In ( 4) both of them are in parallel and forward biased. But in Fig. (1) they are in series but first diode is reverse biased. Hence no current will flow.
