One Kilowatt-hour is equal to—
(1) 3.6 Mega Joule
(2) 3.8 Mega Joule
(3) 3.2 Mega Joule
(4) 4.0 Mega Joule
Answer: (1) The energy 1 kilowatt-hour (kWh) is 3600000 joules or 3.6 megajoules. In physics, energy is an indirectly observed quantity that is often understood as the ability of a physical system to do work on other physical systems. However, this must be understood as an overly simplified definition, as the laws of thermodynamics demonstrate that not all energy can perform work.
