Vedclass · Answer

(A) The circuit consists of a $20 \, V$ $DC$ source,a series resistor of $2 \, k\Omega$,a Zener diode with a breakdown voltage of $6 \, V$,and a load resistor of $6 \, k\Omega$ connected in parallel to the Zener diode.When the Zener diode is in the breakdown region,it acts as a constant voltage source equal to its breakdown voltage.Since the Zener diode is connected in parallel with the load resistor and the output terminals,the voltage across the load resistor is equal to the Zener breakdown voltage.Therefore,the output voltage $V_0$ is equal to the Zener breakdown voltage,which is $6 \, V$.

What is the value of output voltage $V_0$ in $V$ for the circuit shown in the figure?
