Design and fabrication of a LED lamp using potato extract for practical utilization

Renewable Energy

In this study, we have observed the voltage and current of potato extract which are found and grown easily. We have conducted observations very carefully. We have found that the potato extract of these samples have significant amount of voltage and current. The discharge characteristic of a LED lamp was more effective than the other types of lamp as the Open circuit voltage, Short circuit current and Maximum power are more stable and steady in comparison with others. Potatoes contain vitamins, minerals, water, carbohydrate, protein and fiber. It is the presence of the water, sugars and acid within the potato that allows electrons to flow between the metals to form an electrical current. The copper and zinc react effectively forming electrodes, the zinc acts as the electron rich anode ( positive) whilst the electron poor copper acts as the cathode (negative).
