Watt (W) – Defined

The unit of electrical power equal to one ampere under an electrical potential difference of one volt. Electrical potential is like ‘pressure’ in a water piping system.Practical info: A load of one watt would need to operate continuously for 1000 hours – almost 42 days – to consume 1 kilowatt-hour of electricity.
