WebAlthough people have known about electricity since ancient times, they’ve only been harnessing its power for about 250 years. Benjamin Franklin’s electricity experiments – including his famous kite experiment in 1752 – showed just how little we knew about electricity in the era of the American revolution and the first industrial revolution. [1] 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.
