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 Answer
    One 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%.
