JEE PYQ: Semiconductors Question 28
Question 28 - 2020 (09 Jan 2020 Shift 2)
The circuit shown below is working as a 8 V dc regulated voltage source. When 12 V is used as input, the power dissipated (in mW) in each diode is ______.
Show Answer
Answer: 40
Solution
$I = (12 - 8)/400 = 10^{-2}$ A. Power in each diode $= 4 \times 10^{-2} = 40$ mW.
