Question

Find the current through $50\Omega$ resistor :

• A. 0.01 A
• B. zero
• C. 0.02 A
• D. 0.03 A

Answer 1

Answer: (D)

0.03 A

In the above question,A is in forward bias while B is in reverse bias.
The resistance of diode is now in series with $50\Omega and100\Omega$ resistors.(see figure)
The total resistance is hence, $R_{eq}=50+50+100=200\Omega$ (Series connection)
The current hence is $I=\frac{6}{200}=0.03A$
