The range of high resistance is 100 kilo-ohm and above.
Here's a more detailed explanation:
For measurement purposes, resistances are often categorized based on their numerical value. This categorization helps determine the most appropriate measurement techniques and equipment. High resistance values fall into a specific range.
Resistance Categories:
| Category | Resistance Range | Example Use Cases |
|---|---|---|
| Low Resistance | 0 to 1 ohm | Electrical contacts, shunts, heavy conductors |
| Medium Resistance | 1 ohm to 100 kilo-ohms | Heating elements, motor windings, general resistors |
| High Resistance | 100 kilo-ohms and above | Insulation testing, high-voltage circuits |
Therefore, any resistance value equal to or greater than 100 kilo-ohms is considered high resistance. These high resistance values are encountered in applications such as insulation testing of cables and equipment, where the aim is to ensure minimal current leakage. They also appear in certain high-voltage circuits for current limiting and voltage division.
