What is the term for the time required for the capacitor in an RC circuit to be charged to 63.2% of the applied voltage or to discharge to 36.8% of its initial voltage?
Pick an answer to check it.
Answer: B. One time constant
One time constant is the time for a capacitor to charge to 63.2% of the applied voltage, or discharge to 36.8% of its starting voltage. For an RC circuit, it equals R x C.
Tip: One time constant = 63.2%.
