Question

(f) What do you mean by: (i) 1 J energy (ii) 1 W power​

Answer 1

Step-by-step explanation:

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.
