Study Notes
Electricity Basics
- Electricity refers to the flow of electrical charge resulting from the movement of electrons through matter.
- Electrons are negatively charged particles in an atom that are attracted to positively charged protons in the nucleus.
Conductors and Insulators
- Conductors are materials that facilitate the easy transmission of electrical energy from one atom to another.
- Insulators, in contrast, have tightly bound electrons that resist the flow of electrical energy.
Examples of Materials
- Rubber is identified as a non-conductor, meaning it does not effectively transmit electrical energy.
Voltage and Current
- Voltage is defined as the amount of energy required to move an electrical charge between two points.
- Lower voltage corresponds to a reduced flow of electrons.
- Current is the term for the continuous flow of electrons in a circuit and indicates how much electric charge passes a certain point.
Circuits and Power
- A circuit is a closed loop that allows for the flow of electricity to occur.
- The work accomplished by electrons as they move through a circuit is referred to as a load.
- In parallel circuits, electrons can flow through separate paths, allowing multiple routes for electricity.
Measurement of Power
- Power in a circuit is measured in watts, reflecting how quickly energy is used.
Static Electricity
- Static electricity represents the temporary storage of electrical charges on a surface, often noticed as a buildup of charge.
Energy Sources
- A battery serves as a source for providing the necessary energy to mobilize electrons for electrical work.
