It is especially important in some cholesterol abnormalities, the most important one being FH. The higher the number, the greater the risk of an adverse event such as a heart attack or stroke. The lower the number, the lower your risk. HDL-C is the other key cholesterol number you will often hear your doctor mention. Typically, the higher the HDL-C the lower your risk of one of the aforementioned events.
So 1 watt is any ratio of volts x watts that equals 1. 1volt x 1amp = 1 watt. or. 9v @ .11 amps = 1 watt. For ratio of volts x watts above read product of volts x amps. True for resistive loads.
The Watt is the SI unit of power -- Volts times Amperes in direct-current systems, but when dealing with alternating current, if you introduce a reactive (non-resistive) load, Volts and Amps are no longer in phase and trigonometry enters the equation.
