  1. 1. The measurement of electrical current flow, representing the quantity or rate of electrons flowing through a conductor per unit of time, measured in amperes or amps.
  2. 2. The flow of electrons through a conductor, measured in amperes, representing the movement of electrical charge from one point to another in a circuit.
  3. 3. Current Electrical current that reverses direction periodically in a sine wave pattern, typically cycling 60 times per second in North America, commonly used in household and commercial power distribution because it can be easily transformed to different voltages.
  4. 4. The electrical pressure or potential difference that pushes electrons through a conductor, measured in volts, representing the force that causes current to flow in an electrical circuit.
  5. 5. A material that resists or prevents the flow of electrons, such as rubber, plastic, or glass, used to coat conductors and prevent current from flowing where it should not, ensuring safety and proper circuit operation.
  6. 6. The smallest unit of matter that retains the properties of an element, consisting of a nucleus containing protons and neutrons surrounded by orbiting electrons, fundamental to understanding how electricity works at the atomic level.
  7. 7. A positively charged subatomic particle located in the nucleus of an atom, creating the positive charge that attracts and holds electrons in orbit, determining the electrical properties of the element.
  8. 9. Current Electrical current that flows in only one direction continuously with constant polarity, commonly produced by batteries and solar panels, used in electronic devices and DC power systems.
  9. 11. A negatively charged subatomic particle that orbits the nucleus of an atom, responsible for electrical current flow as electrons move from atom to atom through a conductor.
  10. 13. The order of operations for solving mathematical equations (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction), essential for correctly calculating electrical values in complex formulas involving multiple operations like power calculations with series and parallel circuits.
  11. 15. The opposition to the flow of electrons through a conductor or material, measured in ohms, determining how much current will flow for a given voltage according to Ohm's Law.
  12. 20. The order of operations for solving mathematical equations (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction), essential for correctly calculating electrical values in complex formulas involving multiple operations like power calculations with series and parallel circuits.
