In your new job at an engineering company, your supervisor asks you to fabricate a resistor that has a resistance of R = 0.130 Ω and no change in resistance with temperature. She suggests making the resistor from lengths of cylindrical carbon and Nichrome wires of equal radius, placed end-to-end. She wants the combination to fit into a machine that allows for a radius of the resistor to be r = 1.32 mm. What are the lengths of the Nichrome segment and the carbon segment of the resistor (in m)?

In these two examples, what exactly happens if the current goes from left to right? For the first example, when t = 0, where does the charge go? I know that after a long time, the capacitor will fill up and all the current goes through the resistor, but is it the same for t = 0? For the second example, I know that at t=0, all the current goes through the wire, but after a while all the current will go through the resistor?
