What is the unit for electrical resistance?

Explanation:
Resistance is measured in ohms. The ohm symbol is Ω, and by definition resistance equals voltage divided by current (R = V/I). That means if 1 volt drives 1 ampere through a component, its resistance is 1 ohm. The other units correspond to different quantities: amperes measure current, volts measure potential difference, and watts measure power (P = V × I).
