Which of the following is not correctly paired up with its unit of measure?

current/ohms
voltage/volts
charge/coulombs
power/watts

The correct answer is: current/ohms

The units of measurement for electrical quantities have specific associations that are fundamental to understanding basic electrical principles. Current is measured in amperes (or amps), not ohms. Ohms are the unit of measurement for resistance in an electrical circuit, defined by Ohm's Law, which states that the voltage (in volts) across a conductor is proportional to the current (in amperes) flowing through it, with the constant of proportionality being the resistance (in ohms). In contrast, the other pairings are correct: voltage is measured in volts, charge is measured in coulombs, and power is measured in watts. Each of these units represents distinctly different physical quantities, making it essential to associate them correctly to avoid confusion. In summary, the pairing of current with ohms does not follow the established measurement system in electrical engineering, highlighting the importance of understanding proper unit associations for accurate calculations and interpretations in the field.
