Time constant of a circuit is the time in seconds taken after the application of voltage to each___________?
Correct answer: C. 63% of maximum value
- A. 25% of maximum value
- B. 50% of maximum value
- C. 63% of maximum value
- D. 90% of the maximum value
Explanation
For a first-order circuit, the response reaches 1 − e⁻¹ = 0.632 of its final value after one time constant, or about 63%.
