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.f we multiply the watt (the amount of electrical power) by the period of time it is used, we arrive at the amount of electricity consumed. The standard measure of electricity consumption is the amount of watts used over one hour, which is how we get the watt-hour (Wh).
