An array is a special variable, which can hold more than one value at a time. If you have a list of items (a list of car names, for example), storing the cars in single variables could look like this:
milliamps or watt/volt. The SI base unit for electric current is the ampere. 1 ampere is equal to 1000 milliamps, or 1 watt/volt. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between milliamperes and watts/volt. Type in your own numbers in the form to convert the units!
Wattage Wattage is the amount of energy the light uses per hour. In the same family of light bulbs (like incandescents) the higher the wattage the brighter the light is. The disadvantage is that you use more energy. So, if a light bulb is 100 watts, you are using 100 watts of energy per hour.n the same family of light bulbs (like incandescents) the higher the wattage the brighter the light is.
