the physics of wire
The Physics Of Wire
  • Longer Wire = More Resistance
    • Cross-Sectional Area Of The Wires Affect Resistance
    • Material Composition Affects Resistance
    • Pure Resistance Causes A Frequency Independent Voltage Drop
  • Capacitance and Inductance Are Proportional To Wire Length/Construction
    • Impedance Is Defined As The Frequency Domain Ratio Of The Voltage To The Current
    • Parallel Conductors In Wire Express A Reactance That Is Inversely Proportional To Frequency
    • Capacitance and Inductance Cause A Frequency Dependent Voltage Drop
  • Skin Effect Becomes Relevant At High Frequencies Over Longer Runs
