Data Sheet: BATTPRIM.PDF (1) PRIMARY CELLS & BATTERIES Many portable electrical and electronic devices are designed to be powered from batteries and in a lot of cases‚ from primary or non-rechargeable batteries. This is the familiar kind of battery which has a fixed amount of energy stored in it during manufacture‚ and once that energy has been used up the battery is simply thrown away and replaced. There are many different types of primary battery now available‚ each with its own strengths and

If you are looking for instructions about building a lemon battery to light an LED‚ see Lemon Battery at Wikibooks. The lemon battery is a simple type of electrical battery that is commonly made for school science projects because it illustrates a battery’s main components. Typically‚ a piece of zinc metal and a piece of copper metal are inserted into a lemon. Everyday objects such as galvanized nails and copper pennies can be used for the zinc and for the copper. A single lemon is usually studied

attaching it to a battery via jumper cables. The independent variable is the battery charge (1.5 V) and the dependent variable is how fast the motor spins. The lab doesn’t have multiple experiments for us to test this but I would hypothesize that the two variables would have a positive correlation: higher voltage‚ faster spin. I built my tiny motor out of magnet wire‚ a magnet‚ two paper clips‚ a 1.5 V battery‚ and two push pins. I curled the magnet wire around the battery so that it was in a

If there are more coins in the pile‚ then the more electricity it can produce‚ because the more electrons you have‚ the more electricity you will get. Batteries are expensive‚ but you can make one for exactly 24 cents! In this experiment‚ you will make your own voltaic pile using pennies
