Time Constant in AC Circuits Formulas

Time constant is the response representing the elapsed time required for the system response to decay to zero if the system had continued to decay at the initial rate. And is denoted by τ. Time Constant is usually measured using the Millisecond for Time. Note that the value of Time Constant is always positive.

FAQ

What is the Time Constant?

Time constant is the response representing the elapsed time required for the system response to decay to zero if the system had continued to decay at the initial rate. Time Constant is usually measured using the Millisecond for Time. Note that the value of Time Constant is always positive.

Can the Time Constant be negative?

No, the Time Constant, measured in Time cannot be negative.

What unit is used to measure Time Constant?

Time Constant is usually measured using the Millisecond[ms] for Time. Second[ms], Microsecond[ms], Nanosecond[ms] are the few other units in which Time Constant can be measured.
