Definition

Ohms are units used to measure electrical resistance, named after German physicist Georg Simon Ohm who formulated Ohm's Law relating voltage, current, and resistance.

Ohm's Law:

A fundamental relationship in electricity that states the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance.

Superconductivity: The phenomenon where certain materials exhibit zero electrical resistance at very low temperatures.

Kilohms (kΩ) and Megohms (MΩ): Units used to measure large values of resistance, where 1 kilohm equals 1000 ohms and 1 megohm equals 1,000,000 ohms.
