Resistance measured in ohms () VOLT The voltage (or potential difference) between two points 16 the work that must be done to move each coulomb of charge from one point to the other. One volt V of potential difference across resistance of1 creates current of1A WATT watt 1 measurement of the electrical power of device If there .. potential difference of1 across device and current of1A flowing through it then the device operating at power of1 watt (W JOULE joule is a measurement of work an ...
