Answer :
Final answer:
The time constant in a transmission system is the time taken for the response to reach 63.2% of its final value.
Explanation:
The time constant, also known as the first order lag, in a transmission system is the time required (after any dead time) for the response curve to reach a specific percentage of its final value following an upset. In this context, the time constant is the period after which the response reaches 63.2% of its final value.
Understanding the concept of RL circuits and their time constants is crucial because it tells us how rapidly the current reaches a certain percentage of its final value. This is particularly important in the design of electrical and electronic systems where the speed of response to changes is critical.
