Resistors

Using the science behind electricity we can then understand how batteries work. Batteries have two chemical reactions one that produces excess amounts of electron and the second one is a minus balance or a "deficit". These two reactions are separated, but not all batteries have the same chemicals reactions happening, for example disposable batteries have different reactions from rechargeable batteries. Within batteries are currents and they "count" the flow of electrons and are regulated by resistance. Batteries are not the only use of chemical reactions and currents, Led lights also fit into this category. In LEDs currents determine the brightness of the lights, but if the current is too strong the light won't work. To combat this, resistors and resistance guidelines are used. On the package of Leds there is a labeled section outlining the resistor and it color; resistor diagrams also help with understanding and creating light.
