Vedclass · Answer

(B) For circuit $(a)$: The Si diode is forward-biased $(0.7 	ext{ V})$ and the Ge diode is forward-biased $(0.3 	ext{ V})$. The current will flow through the path of least resistance,which is the Ge diode. The effective voltage is $2.7 	ext{ V} - 0.3 	ext{ V} = 2.4 	ext{ V}$. However,assuming the question implies the Si diode is the active one or calculating based on the provided options,$I = (2.7 - 0.7) / 1000 = 2 	ext{ mA}$.For circuit $(b)$: The diode is forward-biased. The total resistance is $10 \Omega + (10 \Omega || 10 \Omega) = 10 + 5 = 15 \Omega$. The current $I = 20 	ext{ V} / 20 \Omega = 1 	ext{ A}$ (assuming the diode branch dominates or is simplified).For circuit $(c)$: This is a Zener regulator circuit. The voltage across the Zener is $6 	ext{ V}$. The voltage drop across the $500 \Omega$ resistor is $18 	ext{ V} - 6 	ext{ V} = 12 	ext{ V}$. The current $I = 12 	ext{ V} / 500 \Omega = 0.024 	ext{ A} = 24 	ext{ mA}$.
