A measure of opposition a material offers to the flow of direct current, measured in ohms, is referred to as ____________.

The term that describes the measure of opposition a material presents to the flow of direct current, expressed in ohms, is known as resistance. Resistance is a fundamental electrical property that quantifies how much a material hinders the movement of electric charge. In a circuit, when a voltage is applied, the resistance determines how much current will flow through the material based on Ohm’s Law, which states that current (I) is equal to voltage (V) divided by resistance (R).

Understanding resistance is essential in various applications, such as designing circuits, selecting components, and ensuring that systems operate effectively and efficiently. It is important to note that resistance is distinct from other concepts related to electrical flow, such as capacitance, reactance, and impedance. Each of these terms pertains to different aspects of electrical behavior and are relevant in alternating current scenarios, but for direct current, resistance is the appropriate term.
