Across
  1. 3. experiment: an experiment or trial that uses controls, usually separating the subjects into one or more control groups
  2. 4. A flow of positive electric charge.
  3. 5. The flow of electricity
  4. 7. A battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices.
  5. 10. the presence and motion of matter that has the property of electric charge.
  6. 14. an instrument used to measure the current in a circuit.
  7. 15. energy: the energy of chemical substances that are released when they undergo a chemical reaction and transform into other substances.
  8. 16. A voltmeter is an instrument used for measuring the electric potential difference between two points in an electric circuit. It is connected in parallel.
  9. 17. An object that attracts iron and some other materials.
  10. 19. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.
  11. 22. circuit: In a series circuit, the current that flows through each of the components is the same, and the voltage across the circuit is the sum of the individual voltage
Down
  1. 1. energy is the power or heat created when something moves, is burned, or is exerted.
  2. 2. An object, substance, or material allowing the flow of an electric charge.
  3. 6. energy: electrically-charged particles and the movement of those particles
  4. 8. The volt (symbol: V) is the unit of electric potential
  5. 9. circuit In a parallel circuit, the voltage across each of the components is the same
  6. 11. variable: any variable that can be attributed a value without attributing a value to any other variable
  7. 12. variable: Dependent variables are things that are affected by the changes that you make—the results of the tests
  8. 13. a diagram, plan, or drawing
  9. 16. Voltage, also known as electric pressure, electric tension, or (electric) potential difference, is the difference in electric potential between two points.
  10. 18. is the unit of electric current in the International System of Units
  11. 20. law: For a given voltage, higher resistance entails lower current flow.
  12. 21. opened and closed: Open circuits allow for electricity to pass through while closed circuits do not.
