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!
The main way electricity consumption is measured is with the unit âwatt-hourâ. A watt (W) is a measure of electrical power. Light bulbs are marked with a watt rating, such as 40 W, and so are appliances like air-blow heaters (around 1,000 W). In fact, most appliances have a compliance badge that will give you an indication of the amount of electrical power it needs to work.
