Resistance is measured in units of __________.

Resistance is measured in units called ohms. The concept of resistance is fundamental in electrical theory, as it quantifies how much a material opposes the flow of electric current. Ohm's Law, which states that voltage equals current times resistance (V = I × R), illustrates the relationship between voltage, current, and resistance in an electrical circuit.

When considering the units of measurement in electricity, it's essential to distinguish between them. Amps measure current, which is the flow of electric charge, while volts measure electric potential or the force that drives this current. Watts represent electrical power, which is the rate at which energy is used or produced. Therefore, in the context of measuring resistance specifically, ohms are the relevant unit, demonstrating the opposition to current flow based on material properties and circuit design.
