Question

Two Zener diodes (A and B) having breakdown voltages of 6 V and 4 V respectively, are connected as shown in the circuit below. The output voltage V0 variation with input voltage linearly increasing with time, is given by :
$\left(V_{\text {input }}=0 \vee\right.$ at $\left.t=0\right)$
(figures are qualitative)

Options

A

B

C

D

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

Voltage across RL increases up to 4 V, then one of the zener diode will blow. So, option (3) is correct.
