Question

A household consumes 4 KWH of energy per day. Express this energy in joules.

Answer 1

3.6*1000000*4=14.4*1000000

Answer 2

Both kilowatt-hour (kWh) and joule (J) are two forms of expressing energy.

One kilowatt-hour of energy is equivalent to 3.6 * 10^6 joules of energy.  

In the given problem, the energy consumed per day in kilowatt-hour is 4 kWh. The corresponding energy equivalent consumed in joules can be given as 4 * 3.6 * 10^6 J.

This implies that the family consumes 14.4 * 10^6 J of energy every day.
