WebThis is when both useful energy transferred and total energy supplied are measured in joules (J). Example The energy supplied to a light bulb is 200 J. A total of 28 J of this is... Web30 mei 2024 · How many joules is one watt? Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it’s running. So a 60W bulb is burning 60 Joules of energy every second you have it turned on.
