Resistance is measured in what unit?

Explanation:
Resistance is measured in ohms. An ohm is the unit that links voltage and current: one ohm equals one volt per ampere (Ω = V / I). This is a direct expression of Ohm’s law, which shows how resistance controls how much current flows for a given voltage. When you test resistance, you’re essentially asking, “How much does this component resist the flow of current at a given voltage?” The other units describe different quantities: watts measure power (the rate of doing work, P = V × I), volts measure electrical potential difference, and amps measure current (the flow of electric charges).
