RC Time Constants-1
What is the term for the time required for the capacitor in an RC circuit to be charged to 63.2% of the supply voltage?
-
An exponential rate of one.
-
Correct AnswerOne time constant.
-
One exponential period.
-
A time factor of one.
What is the term for the time required for the capacitor in an RC circuit to be charged to 63.2% of the supply voltage?
One time constant.
From kd9fni:
1 time constant = time it takes to charge to 63.2% of the voltage, or discharge to 36.8% of the starting voltage.
2 time constants = charge to 86.5% or discharge to 13.5%.
