Fundamentals of Electricity and Current

Electricity and Electrons

• Electricity: A fundamental from of energy resulting from the presence and movement of charged subatomic particles, primarily negativity charged particles ($e^-$)-electronics.
• Electrons: Fundamental, negatively charged subatomu particles that make up all atoms.
• Electric Current: The rate at which electric change flows past a specific point in a circiut.

Energy Conversion and Current Types

• Flashlight Energy Flow: $\text{Chemical E Electrical Light}$.
• Alternating Current: $AC$ - alternating Current Current.
• Direct Current: Found on Battery, noted as $CD \text{ } DC$ - Direct curent.

Conductors and Insulators

• Conductor: A material that allows electric current to flow through it easily and transmits energy.
• Insulator: A materical that heavily restricts the flow of energy, preventing it from easily passing through.
