v2 v3 11 11 12 12 === Voltage === 13 The difference in electrical potential between the two terminals is measured in units of Volts (named after [https://en.wikipedia.org/wiki/Alessandro_Volta Alessandro Volta]). Voltage is *potential* energy, like the lake behind a hydroelectric dam; no work is being done if the water isn't flowing, but you can measure the pressure the water is exerting on the dam. You can use a meter called a voltmeter or a multimeter to measure the amount of voltage "pressure" a battery exerts. 13 The difference in electrical potential between the two terminals is measured in units of Volts (named after [https://en.wikipedia.org/wiki/Alessandro_Volta Alessandro Volta]).
