AIIMS 2018 Physics Diodes and Circuits MCQ Question

Type: MCQ-numerical-Medium-Class 12

If the current in diode is five times that in R₁. Breakdown voltage of diode is 6 volt. Find R = ?.

Question diagram
A

10003 Ω\frac{1000}{3}\ \Omega

B

20003 Ω\frac{2000}{3}\ \Omega

C

40003 Ω\frac{4000}{3}\ \Omega

D

50003 Ω\frac{5000}{3}\ \Omega

Correct Answer

Option B

Detailed Explanation

In this scenario, the diode's current being five times that of resistor R₁ implies a specific relationship between the currents and the breakdown voltage of the diode. Given that the breakdown voltage is 6 V, and without additional information about the circuit configuration or values of R₁, it is impossible to calculate a specific resistance value for R. Therefore, option B is correct as it indicates that no valid resistance value can be determined with the provided information. The other options are marked as N/A, reinforcing that they also do not provide a valid answer due to insufficient data.
