Ohm's law describes the mathematical relationship between which three components?

Answer: B — Voltage, current, resistance

Ohm's law defines the relationship among voltage, current, and resistance in an electrical circuit. It states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor. This relationship can be expressed mathematically as: V = I * R where V is the voltage (in volts), I is the current (in amperes), and R is the resistance (in ohms). This foundational principle is critical to understanding electrical circuits and components, as it allows technicians and engineers to calculate the amount of current in a circuit given its voltage and resistance, or to determine the necessary resistance to achieve a desired current flow, among other applications. The other options involve concepts that are not part of Ohm's law. For example, while power is related to voltage and current, it is not directly governed by Ohm's law. Capacitance and frequency pertain to different areas of electrical theory, such as capacitive circuits and alternating current analysis, which do not directly relate to the simple resistive relationships described by Ohm's law.
