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!
How many milliamps are in an AA alkaline battery? The difference of voltage ratings between the two types of battery is because the alkaline battery starts at 1.5 volts but depletes over time, giving it an average voltage of 1.2 volts, which is the same as the NiMH battery.
