Question

If the $Ge$ diode in the circuit is reverse biased, the current through $2k\Omega$ resistor

• A. increases by $0.2$ mA
• B. decreases by $0.4$ mA
• C. increases by $0.4$ mA
• D. decreases by $0.25$ mA
• E. does not change

Answer 1

Answer: (D)

$\frac{15-0.2}{2}=\frac{14.8}{2}=7.4mn$
$\frac{15-0.7}{2}=7.15mA$
$\therefore I_1-I_2=0.25mA$
