1. The problem statement, all variables and given/known data Hi all. I am looking at a R-C circuit (in series) with DC. I am just trying to analyze what happens at the instant the switch is turned on. If we set up Kirchoff's second law for this system, we can see that the current will not be constant, and this is because the charge of the capacitor builds up. But my question is: When components are added in series, they share the voltage and have the same current. Is this only true when there is not a capacitor in the circuit? Thanks in advance. Regards, Niles.
