How does a megohm reading relate to paint?

A megohm reading measures electrical resistance, indicating how well an insulating material, such as paint, resists electrical current. High megohm values suggest good insulation properties, meaning the paint effectively prevents electrical leakage. This is crucial in applications where electrical safety is a concern, such as in industrial settings or on electrical equipment. Low megohm readings may indicate deterioration or contamination, leading to potential safety hazards.
