Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is Ω .
Key Points
- The ohm (symbol: Ω) is the SI derived unit of electrical resistance.
- It is named after German physicist Georg Simon Ohm.
- An ohm is defined as the electrical resistance between two points of a conductor when a constant potential difference of one volt, applied to these points, produces a current of one ampere.
- The unit is represented by the Greek letter Omega (Ω).
- The concept is essential in understanding and analyzing electrical circuits.
Additional Information
- Georg Simon Ohm
- He was a German physicist and mathematician.
- Ohm is best known for Ohm's Law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points.
- Ohm's Law
- The formula is V = IR, where V is voltage, I is current, and R is resistance.
- It is a fundamental principle used in electrical engineering and physics.
- SI Units
- SI stands for the International System of Units.
- It is the modern form of the metric system and the world's most widely used system of measurement.
- Electrical Resistance
- It is a measure of the difficulty to pass an electric current through a conductor.
- Materials with low resistance are good conductors, while materials with high resistance are good insulators.
