How Does Time Affect Current in a Series RC Circuit?

Click For Summary
SUMMARY

The discussion focuses on the behavior of current in a series RC circuit with an emf source of 120V and a time constant of 4.00 seconds. Initially, the current through the resistor is measured at 8.00 mA. As time approaches infinity, the current will stabilize at 0 A, as the capacitor becomes fully charged and no longer allows current to flow. The mathematical relationship governing this behavior is described by the equation q=Q(1-e^(-t/RC), where Q represents the maximum charge on the capacitor.

A capacitor that is initially uncharged is connected in series with a resistor and an emf source with Є=120v and negligible internal resistance. Just after the circuit is completed, the current through the resistor is 8.00 mA, and the time constant for the circuit is 4.00 s

What is the current as time reaches infinity? prove mathmaticly

My questions is don't know where to start I know it has something to do with q=Q(1-e_-t/RC) but must be missing something

Welcome to the forums Ryll,

I'll give you two hints. Firstly, current is the rate of flow of charge. And secondly, one could make good use of limits in this question :wink:
