What is the basic unit of measure for electrical resistance?

• A. Volt
• B. Ohm
• C. Ampere
• D. Farad

Answer: (B)

The basic unit of measure for electrical resistance is the Ohm. This unit quantifies how strongly a material opposes the flow of electric current. In practical terms, when a voltage is applied to a conductor, the resistance in Ohms will determine how much current flows through that conductor according to Ohm's Law, which states that Voltage (V) = Current (I) multiplied by Resistance (R). This relationship is foundational in electrical engineering and plays a crucial role in understanding and designing electrical circuits. The other units mentioned—Volt, Ampere, and Farad—are related to different electrical properties. The Volt measures electric potential or voltage, the Ampere measures electric current, and the Farad measures capacitance, which is a completely different aspect of electrical systems. Each unit plays its unique role in the field of electronics, but when it comes specifically to resistance, the Ohm is the appropriate measure.
