Definition

A unit used to measure how much a material resists the flow of electric current, defined as the resistance that allows one ampere of current to flow when one volt is applied.

Example

The resistor in the circuit has a value of 10 ohms.

Conversation

I was reading about electricity and found out that one ohm is the resistance in a circuit.

That's interesting! I always wondered how they measure that.

Yeah, it’s pretty cool how a single ohm can affect current flow.

Exactly! Understanding that helps a lot with electronics.

Root Explanation

Ohm → The word 'ohm' is named after the German physicist Georg Simon Ohm, who formulated Ohm's Law, which relates voltage, current, and resistance in electrical circuits. It is a unit of measurement for electrical resistance in the International System of Units (SI).

Memory Tip

Think of Georg Simon Ohm, the scientist who helped us understand electricity, to remember that an 'ohm' measures electrical resistance.
