The answer is C = 1/R = 12.346
Solution:
1/R(5) = 1/0.405
1/R = 5/0.405
C = 1/R = 12.346
The time constant of an inductive circuit is the time it takes for the voltage across the inductor to reach 63% of its initial value. If a fraction of the total flux is linked between two coils, the amount of flux linkage can be defined as the fraction of the total flux linkage possible between the coils.
This fractional value is called the coupling coefficient and is given the letter k. An argument is deductive if the argument believes that the truth of the premises reliably establishes the truth of the conclusion. An argument is inductive if the argument believes that the truth of the premises only provides good reason to believe that the conclusion is likely to be true.
