Vedclass · Answer

(B) In the given circuit,the diodes are in parallel. The diode with the lower threshold voltage will conduct first. Case $1$: Initially,the $Ge$ diode (threshold $0.3 \, V$) conducts. The output voltage $V_{01} = 12 \, V - 0.3 \, V = 11.7 \, V$. Case $2$: If the $Ge$ diode connection is reversed,it will be reverse-biased and will not conduct. Now,the $Si$ diode (threshold $0.7 \, V$) will conduct. The output voltage $V_{02} = 12 \, V - 0.7 \, V = 11.3 \, V$. The change in the value of $V_0$ is $\Delta V_0 = |V_{01} - V_{02}| = |11.7 \, V - 11.3 \, V| = 0.4 \, V$.

$Ge$ and $Si$ diodes conduct at $0.3 \, V$ and $0.7 \, V$ respectively. In the following figure,if the $Ge$ diode connection is reversed,the value of $V_0$ changes by how many volts?
