Much of Chile is included in the Chilean Winter Rainfall-Valdivian Forests biodiversity hotspot (CEPF). In addition to mainland areas this hotspot includes the island ecoregions of the Juan Fernandez FernÃ¡ndez Islands Temperate (EoE) eoe and The San-Felix FÃ©lix San Ambrosio Islands (EoE) . forests eoe
Cars have voltage regulators that maintain their battery's charge. A multimeter, which can be used to measure voltage. An automobile engine's alternator essentially serves as an electric generator. The power generated by the car's charging system is also used to run the car's electrical systems, such as its headlights.
12V is fine. Also, the thought of using resistors as a voltage divider has brought up the fact that the battery may only last as long as a 5v. NO!!! A voltage divider is OK for low-current signals, but it's a bad idea for a power-supply reducer.In fact, with a 12V supply, you've to 7V across the regulator,and 5V across the load and there is more power used in the regulator.). Switching regulators are more efficient. With a switching regulator, the current from the supply/battery actually decreases if you boost the voltage.
