Ques. 1JEE Main 2024, 30 January (Evening Shift)

[figure] In the given circuit, the voltage across load resistance (RL) is :

  1. 8.75 V
  2. 9.00 V
  3. 8.50 V
  4. 14.00 V

Answer

(1) 8.75 V

Solution

Both diodes are forward biased; drop across Ge = 0.3 V, across Si = 0.7 V.

i= 15-0.3-0.7(1.5+2.5) k = 14 V4 k =3.5 mA

VL=iRL=3.5 mA 2.5 k =8.75 V

Answer: (1)
