Isn't KCL Kirchhoff's Current Law which states that currents that join at a junction/node must be combine to equal the third current? And KVL is Kirchhoff's Voltage Law which is the summing of all the voltage changes in each object in the circuit? Because the equation I wrote is certainly a...

I'm having a bit of trouble getting started... So I've labeled I_1 as the current in the batt-resistor loop, I_2 as the current in the RC loop, and I_3 as the current in the resistor/switch branch. My small amount of work so far: I_1+I_2=I_3 \\ \frac{V_1}{R_1}+\frac{V_2}{R_2}...

Would I have to write a Kirchhoff equation?

So what happens if there is a resistor on the branch with the switch?

OK, so if I'm getting this correctly, the current from the capacitor reaches the junction and it all turns into that segment because there's no voltage to drive some charge away. Is that right? Thanks for the quick reply, by the way.

Homework Statement The bit I'm struggling with is to determine the time constant \tau for the referenced circuit after the switch is closed. Constants are given in the image, which can be found at https://www.physicsforums.com/attachment.php?attachmentid=12737&d=1203627574. Homework...
