What type of current flow is opposed by resistance?

• A. Direct current
• B. Alternating current
• C. RF current
• D. All these choices are correct

Answer: (D)

Resistance is a property of materials that opposes the flow of electric current, and this opposition is present regardless of the type of current. Whether we are dealing with direct current (DC), alternating current (AC), or radio frequency (RF) current, resistance plays a role in the amount of current that flows through a circuit. Direct current refers to the unidirectional flow of electric charge, where electrons move consistently in one direction. Alternating current, on the other hand, involves the periodic reversal of direction of electron flow, but it is still subject to the same resistive effects. RF current is a form of alternating current that specifically refers to frequencies used for radio communication, and it also encounters resistance in conductors. Since resistance affects all types of current flow, it is accurate to say that all these types of current are opposed by resistance, making the answer correct. Understanding this foundational principle is essential in electronics and radio communications, as it underlies the behavior of circuits and the design of equipment.
