What is the basic unit of resistance?

The basic unit of resistance is the Ohm. Resistance is a measure of the opposition to the flow of electric current within a circuit. According to Ohm's Law, the resistance (measured in Ohms) is equal to the voltage (in Volts) divided by the current (in Amperes). This fundamental relationship is essential for understanding how circuits function and how various components within those circuits interact.

The other units mentioned refer to different electrical properties: Joules measure energy, Farads measure capacitance (the ability of a component to store an electrical charge), and Amperes measure current (the flow of electric charge). Each term plays a significant role in electrical engineering and physics, but when it comes to the specific question of resistance, the Ohm is the correct and designated unit of measurement.
