13. Two ideal diodes are connected to a battery as shown in the circuit. The current supplied by the battery is :

[2012]

(a) $0.75 A$

(b) zero

(c) $0.25 A$

(d) $0.5 A$

Show Answer

Answer:

Correct Answer: 13. (d)

Solution:

  1. (d) Here $D_1$ is in forward bias and $D_2$ is in reverse bias so, $D_1$ will conduct and $D_2$ will not conduct. Thus, no current will flow through $D C$.

$I=\frac{V}{R}=\frac{5}{10}=\frac{1}{2}$ Amp.
