A current-carrying wire produces an electric field outside itself
Is it true that a current-carrying wire produces an electric field outside itself?
That a current-carrying wire produces an electric field outside itself (due to surface charges establishing the potential gradient along the conductor) is a fundamental result of electrodynamics, making citation unnecessary.
Verdict: COMMON KNOWLEDGE · 0 sources for, 0 against · Last checked
The claim is a standard piece of electrodynamic physics regarding steady currents in wires and the associated surface charges required to maintain the electric field, which represents a basic physical principle and everyday observation of circuit behavior, thus qualifying as common knowledge.
