Static is caused by the transfer of electrons from one object to another. Transferring electrons can create an imbalance in the charge of the atoms in the two objects, making one more positive and one more negative, effectively attracting them to each other.Continue Reading
All material is made up of atoms. Atoms are comprised of positively charged protons, neutral neutrons and negatively charged electrons. Most of the time, atoms have equal numbers of protons and electrons and have a neutral charge.
When atoms come in contact with other atoms, electrons may transfer between them. An uneven transfer of electrons can create a positively or negatively charged atom. Atoms do not like to remain charged. An excess of electrons is discarded when the atom comes in contact with another atom with the opposite charge. The extra electrons will jump from one atom to another to achieve neutral charges. Sometimes, this jump is accompanied by a tingle or shock.
Some materials are more likely to accept additional electrons than others. Other materials are more likely to give up electrons. When these two differing types of objects come in close contact, static can easily be seen. Silk and glass are two excellent examples of materials that transfer electrons easily causing static.Learn more about Electricity
The Peltier effect occurs when two dissimilar conductors form an electric junction, causing electrons to flow in a specific direction that generates heat on one side of the junction and cold on the other side. The junction uses two types of conductors, one rich in electrons (n-type) and one that can accept electrons (p-type).Full Answer >
Electricity is the flow of electrons through a conductor. Materials that conduct electricity easily have a weak hold on their outermost electrons, allowing them to move easily from one atom to another. When an electron moves to an adjacent atom, it displaces another electron, and this flow is electric current.Full Answer >
According to an experiment reported at Exploratorium, a pickle can be used as an energy source to power small devices such as a light bulb or buzzer because of its ability to push and pull electrons. The pickle is high in salts and electrolytes, which can react to move electrons.Full Answer >
A lemon battery uses the juice inside the lemon as an electrolyte to facilitate electrons moving between a pair of electrodes inserted into the fruit. These need to be two dissimilar metals, such as a copper penny and zinc-coated nail. Completing the circuit creates a weak electrical current.Full Answer >
