BITSAT Physics Question (2022) — Solution

Question

In the circuit shown assume the diode to be ideal. When V_i increases from -2 ~V to 6 ~V , the change in current is (in mA )

Options

  1. A. Zero
  2. B. 20
  3. C. 25 8
  4. D. 32

Answer

B. 20

Step-by-step solution

l_ initial =0 for V_i +1 ~V This diode conduct only beyond V_i=+1 ~V I_ final = 5 250 =0.02 ~A So, change in I=0.02 ~A =20 ~mA
