Power of radio (P) = 15 watt =\( \frac{15}{1000}\) = 0.015 KWH
Number of radio (N) = 1
Time of consumption in one month (t) = 8 * 30 = 240 hours
Now energy consumption (E) = P * N * t
= 0.015 * 240
= 3.6 KWH
In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity.Energy consumption refers to ALL the energy used to perform an action, manufacture something or simply inhabit a building. ... In a factory, total energy consumption can be measured by looking at how much energy a production process consumes, for example, by making car parts. This will include water, electricity, gas
