Basic Acoustics Speaker Polarity A look at speaker systems and phase and polarity. The definition of a phantom center and the Law of the First Wavefront are presented. The problem with localizing in a car audio system are discussed. This article concerns the flow of current through a conductor.
Electrical currents cause magnetic fields.
Magnetic flux, magnetic induction and co-axial signal cables are discussed. Resistance of Cylindrical Wires Basic Electronics Using the CRC Handbook to determine the resistance of large gauge power cables. The difference between contesting and real-life requirements. As a capacitor discharges through a resistance, the voltage across the cap drops. This time can be calculated and very useful for car audio applications.
