WebThe ohm is the electrical unit of resistance. One ohm is defined as the resistance between two points of a conductor when 1 volt is applied and a current of 1 ampere is flowing. 1 \,\text {ohm} = 1\,\text {volt}/\text {ampere} 1ohm = 1volt/ampere. We've now defined, in order, a basic set of our favorite electrical units. WebA common unit of electric current is the ampere, which is defined as a flow of one coulomb of charge per second, or 6.2 × 10 18 electrons per second. The …
