The charging time constant of a circuit consisting of an inductor is the time taken for the voltage in the inductor to become __________% of the initial voltage.
  • a)
    33
  • b)
    63
  • c)
    37
  • d)
    36
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
The charging time constant of a circuit consisting of an inductor is t...
We know that: V=V0(1-e-t /time constant).
When time constant=t, we have: V=V0(1-e-1)= 0.63*V0.
Hence the time constant is the time taken for the charge in an inductive circuit to become 0.63 times its initial charge.
