jasonhanjk 0 Report post Posted November 29, 2003 Introduction of these 3 components would make the voltage / current in the headphone oscilate. As time tends to infinite (or one hour warm up ), the oscilates tends to zero. It's this principle that gives rise to the following argument :- Q= What's the best length for a power cord? Someone answered: 1.5-2m is preferred for the oscillations to settle down. Oops, miss this post. Maybe. The longer the cable run, the more capacitance and inductance is being introduced. The interesting thing is, introducing a certain length of cable at frequency of 50Hz (Singapore power). Both capacitance and inductance will cancer each other mathematically. Giving you a pure resistor than is around 0.08 ohm. A pure resistor does not oscillates. I once done an experiment at my office. Using a meter of pure 0.8mm silver wire and a 1.0mm enamel copper and measure their properties at 50Hz. The results show that they are identical in resistance and inductance. No capacitance since I need 2 wire in parralel to do that. Share this post Link to post Share on other sites
