Volts are units of potential difference similar to the pressure in the circuit. Voltage is the type of pressure that pushes an electrical charge through a circuit. 21. Proton A. The act of bringing about something (especially at an early time). B. Atomic particle in the nucleus of an atom with a positive charge C. anything that will attract or pull iron, steel, and certain other metals to it D. Something that gives power to make things work Name Date Day#27 22. induction A.

The smallest component of an element having the chemical properties of the element. D. Volts are units of potential difference similar to the pressure in the circuit. Voltage is the type of pressure that pushes an electrical charge through a circuit. 26. Charge A. Atomic particle in the nucleus of an atom with a positive charge B. An object that attracts iron and steel. C. the measure of extra positive or negative particles that an object has. D. Alternators (AC) send alternating current that switches directions. As the magnets spin in the machine, they pass the wires going up on one side and down on the other side. The result is a current that changes direction. 27. Insulator A. The path along which energy travels. B. a tiny piece of any element. C. A type of material that tries to prevent the flow of thermal energy. D. A form of energy that is used in homes and is produced by the movement of electrons. 28. Conductor A. (DC) A flow of electrons that moves in only one direction through a circuit. B. Material that allows current to easily flow. C. particle in an atom that has a negative electrical charge D. can be turned on and off 29. Neutron A. The act of bringing about something (especially at an early time). B. A magnet created when electric current flows through a coil of wire. C. Particle in an atom that has no charge. D. Something that gives power to make things work 30. Electron A. Material that allows current to easily flow. B. particle in an atom that has a negative electrical charge C. Alternators (AC) send alternating current that switches directions. As the magnets spin in the machine, they pass the wires going up on one side and down on the other side.
