Options

  1. AGiven below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A : A
  2. BGiven below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A : A
  3. CGiven below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A : A
  4. DGiven below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A : A

Correct answer

D. Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A : A

Step-by-step solution

In option (4), 1015=105+RD\frac{10}{15}=\frac{10}{5+R_D} The diode can conduct and have resistance RD=10ΩR_D=10 \Omega because diode have dynamic resistance. In that case bridge will be balanced
