Irradiance is a measurement of solar power and is defined as the rate at which solar energy falls onto a surface. The unit of power is the Watt (abbreviated W). In the case of solar irradiance, we usually measure the power per unit area, so irradiance is typically quoted as W/m²,...
However, in science, energy and power are different units of measurement. A handy way to understand this difference is to think of energy as an amount of resource, like money, and power as the rate of spending it. For example, a heater with a power rating of 2 kilowatts ‘spends’ 7.2...
The three most basic units in electricity are voltage (V), current (I, uppercase "i") and resistance (R). We measure voltage in volts, current in amps and resistance in ohms. What Is a Volt? Voltage is a measurement of the electric potential or "pressure" at which electricity flow...
Rømer actually observed the transits at other times than conjunction, and Huygens used more complicated trigonometry than what was presented here to infer a measurement for the speed of light in terms of the astronomical unit (which they had begun to measure a bit more accurately than in ...
