When measuring high-resistance components, which unit would you primarily use?

When measuring high-resistance components, the megohm is the most appropriate unit to use. This is because high-resistance components, such as insulators and other electrical devices designed to have significant resistance, often have resistance values that extend into the megohms range.

For example, insulators in electrical systems typically need to prevent current from flowing, which requires them to have resistances that may be measured in millions of ohms. Using megohms allows for a more concise and manageable way to express these large values, as opposed to using ohms, which would require larger numerical representations.

While kiloohms can be appropriate for moderately high resistances, they do not adequately cover the higher ranges that are often found in components like high-voltage insulators or circuit breakers. Microohms, on the other hand, are used for very low resistances, particularly in precision applications, and would not apply when looking for high resistance measurements. Thus, the megohm is the standard unit in this context, making it the most suitable choice for measuring high-resistance components.
