Which condition is NOT necessary for Static Arc Ignition?

Static arc ignition occurs when an electrical discharge, generated by static electricity, ignites a fuel source. For this phenomenon to take place, specific conditions must be present.

The correct answer, relating to static arc ignition, indicates that a very high temperature is not necessarily required. Static electricity can generate a spark at a temperature that is much lower than that of many other ignition sources. This means that even a relatively minor spark can ignite certain flammable materials if the conditions are right (such as an appropriate fuel source and an accumulation of static charge).

In contrast, conditions like a means of static generation and a means of accumulating and maintaining the charge are essential for creating the static electricity necessary for ignition. Without these, static arcs will not form. The presence of a fuel source is also critical, as there must be a combustible material available for the ignition source to act upon.

Thus, while temperature plays a role in combustion, it is not a defining factor for static arc ignition, making the identification of high temperature as unnecessary accurate in this context.
