Frequently Asked Questions
What is the relationship between Ohms, Kiloohms, and Megaohms?
Resistance metric prefixes scale by factors of 1,000. One Kiloohm (kΩ) equals 1,000 Ohms (Ω), and one Megaohm (MΩ) equals 1,000 Kiloohms or 1,000,000 Ohms.
How does resistance affect current and voltage?
According to Ohm’s Law (I = V / R), for a fixed voltage, electric current is inversely proportional to electrical resistance. Doubling the resistance cuts the circuit current in half.
Why is high resistance important in insulation testing?
Electrical insulation must exhibit very high resistance (typically tens or hundreds of Megaohms) to prevent hazardous leakage currents between energized conductors and equipment chassis ground.
