1. The problem statement, all variables and given/known data Type P241B coaxial cable has an inductance of 0.4 μH/m and a capacitance of 40 pF/m. The diagram below shows a 100 m length of this cable connected to a battery and switch at the sending end and a 50Ω resistor at the receiving end. (a) If S is closed, what initial current will flow from the battery? (b) How long will it take before this current changes? (c) What will be the battery current at t=∞? 3. The attempt at a solution I calculated the effective resistance of the cable to be 100 ohms. Since this is in series with a 50 ohm resistor then the total resistance is 150.
