Question

In the figure shown below,

The $V_{out}$ of the circuit is _____. (Assume the cut in Voltage of the diode $V_{\gamma }$ = 0.7 V)

• A. 6.2

Answer 1

The correct option is A 6.2
The above circuit can be represented as,


Applying KCL at node 1,

$\frac{V_0}{2k}+\frac{V_0-10+0.7}{2k}+\frac{V_0-10+0.7}{2k}$ = 0

$V_0\left[\frac{3}{2k}\right]=\frac{9.3}{1k}$

$V_{out}=\frac{9.3}{3}\times 2$
= 6.2 V
