What unit is electrical resistance typically measured in?

Electrical resistance is typically measured in ohms, represented by the symbol Ω. Ohm's Law defines the relationship between voltage (measured in volts), current (measured in amperes), and resistance, illustrating that voltage equals current times resistance. This fundamental relationship emphasizes that resistance is a measure of how much a material opposes the flow of electric current.

In contrast, volts measure electrical potential difference, amperes measure the flow of electric charge, and hertz measure frequency. These units have distinct roles within electrical systems, with ohms specifically designated to quantify resistance, making it the appropriate answer for this question.
