Current will only flow through a capacitor until it reaches the same voltage as the source. If you apply a DC voltage to the RC circuit, current flows only until the capacitor charges up (you're measuring your voltage drop across the resistor?). Then the circuit reaches an equilibrium where the capacitor becomes an open circuit. Your lab is measuring how long this takes?naissa said:I am doing a lab on RC circuits and I do not understand anything about it.
In the lab, I charged an discharged a capacitor. The voltage decreased with the equation V=Voe^(-t/RC)
Can you explain me this lab?
