How is energy measured
Web20 dec. 2013 · For example, we may be interested to know the amount of electricity needed to power a LCD monitor as opposed to a CRT monitor. Both of these applications are different and have different tolerances. Thus the amount of electricity driving these devices will also be different. A given signal’s size can be measured in many ways. WebIt can be measured by using a pyrheliometer. Pyrheliometers measure ‘direct solar radiation’ E: the amount of solar energy per unit area per unit time incident on a plane …
