What is the SI unit of electric resistance?
A. Volt
B. Ohm✓ Correct Answer
C. Ampere
D. Watt
💡 Solution & Explanation
The SI unit of electric resistance is the ohm, named after the German physicist Georg Simon Ohm, who formulated Ohm law relating voltage, current, and resistance. Volt measures electric potential difference, ampere measures electric current, and watt measures power. Resistance quantifies how strongly a device or material opposes the flow of electric current.
