  1. 2. - In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge in one or more directions. Materials made of metal are common electrical conductors
  2. 7. circuit-A parallel circuit is one that has two or more paths for the electricity to flow, the loads are parallel to each other.
  3. 8. - A proton is a stable subatomic particle, symbol p , H⁺, or ¹H⁺ with a positive electric charge of +1 e. Its mass is slightly less than that of a neutron and 1,836 times the mass of an electron. Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons
  4. 9. - An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume
  5. 12. current- Alternating current is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current, which flows only in one direction
  6. 13. loop- In control theory, an open-loop controller, also called a non-feedback controller, is a control system in which the control action is independent of the "process output", which is the process variable that is being controlled
  7. 15. The watt (abbreviated W) is the International System of Units' (SI) standard unit of power (energy per unit time), the equivalent of one jouleper second. The watt is used to specify the rate at which electrical energy isdissipated, or the rate at which electromagnetic energy is radiated, absorbed, or dissipated.
  8. 16. loop- In control theory, a closed-loop transfer function is a mathematical function describing the net result of the effects of a feedback loop on the input signal to the plant under control
  9. 18. often shortened to amp, is the unit of electric current in the International System of Units. One ampere is equal to 1 coulomb or 6.241509074×10¹⁸ electrons worth of charge moving past a point in a second
  10. 20. - Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact
  11. 21. continuous physical force exerted on or against an object by something in contact with it.

  1. 1. power"
  2. 3. resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses
  3. 4. A kilowatt-hour is a unit of energy: one kilowatt of power for one hour. In terms of SI derived units with special names, it equals 3.6 megajoules. Kilowatt-hours are a common billing unit for electrical energy delivered to consumers by electric utilities
  4. 5. the unit of electric potential, electric potential difference, and electromotive force in the International System of Units
  5. 6. nucleus-n electron is a negatively charged subatomic particle that can be either bound to an atom or free (not bound). An electron that is bound to an atom is one of the three primary types of particles within the atom
  6. 10. - The smallest part of a substance that cannot be broken down chemically. Each atom has a nucleus (center) made up of protons (positive particles) and neutrons (particles with no charge). Electrons (negative particles) move around the nucleus.
  7. 11. electrical insulator is a material in which electric current does not flow freely. The atoms of the insulator have tightly bound electrons which cannot readily move. Other materials—semiconductors and conductors—conduct electric current more easily.
  8. 12. electromotive force or potential difference expressed in volts.
  9. 14. a container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power.
  10. 17. circuit- A series circuit is a simple pathway that lets electrons flow to one or more resistors. A resistor is anything that uses power from a cell (battery). Usually, in a series circuit, a bulb acts as the resistor.
  11. 19. current -Direct current is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams
