The unit of electrical resistance is measured in

Explanation:
Resistance is the opposition to current flow in a circuit. The unit used for this opposition is the ohm, defined as the amount of resistance that lets one ampere of current flow when one volt is applied. In other words, 1 ohm equals 1 volt per ampere (Ω = V / A). The symbol for the unit is the omega (Ω). Watts measure power, volts measure electrical pressure (potential difference), and amps measure current. So when you’re asked for the unit of electrical resistance, the correct term is the ohm. For example, if you have 5 volts across a component and 0.5 amps flow through it, the resistance is 5 V / 0.5 A = 10 Ω.
