Semiconductor Electronics Materials Devices And Simple Circuits Ques 18
18. 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) 0
(c) $0.25 A$
(d) $0.5 A$
Show Answer
Answer:
Correct Answer: 18.(d)
Solution:
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, current will flow through $D C$.
$I=\frac{V}{R}=\frac{5}{10}=\frac{1}{2}$ Amp.
