A series RLC filter for 10kHz is being designed using a 0.01mF capacitor. The discussion highlights confusion regarding the circuit diagram and the correct orientation of the resistor, inductor, and capacitor. Participants note the need for clarity in the thread title, which initially suggested a different problem. There is also a request for clarification on whether the capacitor value is in microfarads or millifarads. Overall, the focus is on accurately designing the filter and presenting the circuit diagram effectively.
