Volts, Amps and Watts explained
Volts, Amps and Watts are the three most important measurements when working with electricity. Here is a quick refresher on what they each represent.
Volts = Strength
Amps = Flow of electric current
Watts = Electrical power; the combination of volts and amps
Wattage is a measure for the power of an electrical system, it is simply the combination of Volts and Amps. To calculate wattage multiply the voltage by the amps.
Watts = Volts x Amps
The flowing water analogy is commonly used to explain Volts and Amps but I find it confusing since water pressure will have an effect on the water flow volume so how can pressure and flow be individual metrics?
Instead I prefer the warriors analogy:
I'm going to use soldiers for this analogy. A high voltage will mean a strong soldier where as a low voltage will mean a weaker soldier.
A soldier with high voltage with be a better fighting force
The effect of one soldier here is high.
Whereas a soldier with a low voltage will not be as effective.
Lets put some real life examples to these numbers.
|North American power socket||120v||12A max|
|European & Commonwealth power socket||230-240v||13A|
