Briefly explain Ohm.

### The Ohm is the measurement of resistance in an electrical circuit.

## Step1: Understanding Ohm### Ohm is a unit of measurement in the International System of Units (SI). It is used to measure the electrical resistance, impedance, or reactance in an electrical circuit.## Step2: Defining Resistance### Resistance is a measure of the opposition to the flow of electric current in a circuit. It determines how much the electrical component will resist the flow of electrons.## Step3: Relating Ohm and Resistance### The Ohm is named after the German physicist Georg Simon Ohm. He formulated Ohm's Law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. This relationship is usually formulated as , where is the voltage, is the current, and is the resistance.
