What is a megaohm?

Explanation:
Megaohm means a million ohms. The prefix mega- denotes 10^6, so a megaohm equals 1,000,000 ohms. The other values are smaller scales: 1,000 ohms is a kilohm, 10,000 ohms is ten kilohms, and 100 ohms is simply 100-ohms. In insulation resistance tests, readings in the megohm range typically indicate good insulation, while lower values indicate leakage.
