Question

Assuming that the two diodes $D_1$ and $D_2$ used in the electric circuit shown in the figure are ideal, find out the value of the current flowing through $1\Omega$ resistor.

• A. 2 A
• B. 3 A
• C. 4 A
• D. 5 A

Answer 1

The correct option is A 2 A

In given circuit $D_2$ is reverse baise therefore, current will not flow from this diode.

Now

$R_{eq}=2+1=3\Omega$

$V=6V$

Current will flow in this circuit is,

$I=\frac{V}{R_{eq}}=\frac{6}{3}=2A$
