- Basic electrical terms and definitions - Understand the concepts of voltage, current, and impedance.
- Basic concepts of electricity
- Basic Electrical Theory: The Fundamental Laws of Electricity A strong foundation for any electrical worker is built on a thorough knowledge of the laws that govern the operation of electricity.
- Static Electricity It was discovered centuries ago that certain types of materials would mysteriously attract one another after being rubbed together.
- Conductors, Insulators, and Electron Flow It must be understood that not all conductive materials have the same level of conductivity, and not all insulators are equally resistant to electron motion.
- Electric Circuits A circuit is an unbroken loop of conductive material that allows electrons to flow through continuously without beginning or end.
- Voltage and Current Voltage is the measure of "push" available to motivate electrons. Current is the "flow" of electrons.
- Resistance A short circuit is an electric circuit offering little or no resistance to the flow of electrons. Resistance is the measure of opposition to electric current.
- Conventional Versus Electron Flow In conventional flow notation, an electric charge moves from the positive (surplus) side of the battery to the negative (deficiency) side. In electron flow notation, an electric charge moves from the negative (surplus) side of the battery to the positive (deficiency) side.
- Basic Electrical Terms and Definitions Understanding electricity requires knowledge of these basic electrical terms.
- Ohm's Law
- Ohms Law: How voltage, current, and resistance relate Ohm's Law is a very simple and useful tool for analyzing electric circuits. It is used so often in the study of electricity and electronics that it needs to be committed to memory by the serious student.
