How to make a lemon battery A lemon battery is made with lemon and two metallic such as copper and zinc. Copper and zinc work well together with lemon to make lemon battery because lemon contain citric acid similarly Tomatoes and other citrus fruits contain enough acid to effect the galvanometer. How to make a lemon…
Diy resistor from lead pencil Diy resistor from lead pencil ,This is a demonstration of variable resistance. The core of a lead pencil does n’t lead at all but it’s the graphite which conduct the whole process. Graphite will conduct electric current, but not as near as copper. Because it resists the flow of current,…
How to make an Electroscope How to making of an Electroscope : The electroscope is an easy-to-make device and should not be difficult to assemble for students who are motivated. They can use it to demonstrate the presence of an electrostatic charge in a comb, a balloon, or other charged object. As the charged object…
