JEE PYQ: Current Electricity Question 35
Question 35 - 2020 (09 Jan 2020 Shift 2)
The current $i$ in the network is:
(1) 0.2 A
(2) 0.6 A
(3) 0.3 A
(4) 0 A
Show Answer
Answer: (3)
Solution
Both diodes are reverse biased, so no current flows through $5,\Omega$ and $20,\Omega$. Two resistors of $10,\Omega$ and two of $5,\Omega$ are in series. $I = \frac{V}{R_{\text{eq}}} = \frac{9}{10+5+10+5} = \frac{9}{30} = 0.3$ A.
