Meaning and Definition
The minimum voltage required to cause an electric spark to jump across a gap between two electrodes.
In a broader technical context, it can refer to the threshold voltage at which dielectric breakdown occurs in an insulating medium, initiating a conductive path. It is a critical parameter in the design and safety of electrical systems, ignition systems, and high-voltage equipment.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Spelling conventions follow national norms (e.g., 'sparking' vs. 'sparking' is the same).
Connotations
Identical technical connotations in both varieties.
Frequency
Equally low-frequency and specialized in both UK and US technical English.

- Using 'spark voltage' (less common). Confusing it with 'operating voltage'. Using it as a verb (e.g., 'The system is sparking voltage').
FAQ
Frequently Asked Questions
In most technical contexts, yes, they are synonymous. 'Sparking voltage' is often used specifically when the breakdown results in a visible spark (e.g., in air), while 'breakdown voltage' is a more general term for dielectric failure.
Typically, it is used for gases (like air). For solids and liquids, the more general term 'breakdown voltage' or 'dielectric strength' (voltage per thickness) is preferred.
In a petrol engine's spark plug. The ignition coil must generate a voltage higher than the sparking voltage of the plug gap to ignite the fuel-air mixture.
Yes, significantly. Higher humidity generally lowers the sparking voltage in air because water molecules facilitate the ionization process leading to a spark.
The minimum voltage required to cause an electric spark to jump across a gap between two electrodes.
Sparking voltage is usually technical/specialized in register.
Sparking voltage: in British English it is pronounced /ˈspɑːkɪŋ ˌvəʊltɪdʒ/, and in American English it is pronounced /ˈspɑrkɪŋ ˌvoʊltɪdʒ/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Imagine a SPARK needing a push (VOLTAGE) to jump across a gap. The 'sparking voltage' is the exact strength of that push needed.
Conceptual Metaphor
THRESHOLD (The voltage is a threshold that must be crossed to initiate an event/spark).
