# What does it mean to have a large time constant of a RC network than the time period of an input AC signal

What does it mean to have a large time constant of a RC network than the time period of an input AC signal?

Can someone tell me how to understand this and what sense does it make?

• Trying to decompose this pretty broad question into smaller steps: so, do you understand what the importance of time constant for RC filters is? Dec 7, 2021 at 16:53
• yes. I was reading about clamper circuits and found this term which I didn't understand. I understand that the time constant of an RC circuit is the time the RC network takes to get charged to 63.2% value of the input voltage. Dec 7, 2021 at 16:59

• Correct @Newbie except if the frequency is much much less than the cut-off frequency = $\dfrac{1}{2\pi RC}$ Dec 7, 2021 at 17:07
