Across
  1. 1. A combination of two or more electrochemical cells in a series
  2. 5. OFF--there is a break in the circuit, so electricity cannot flow through it.
  3. 6. A device used to measure potential difference (voltage)
  4. 10. A resistor whose value can be varied between its minimum and maximum values.
Down
  1. 2. A device used to measure current in a circuit
  2. 3. ON--The switch completes the circuit, so electricity can flow through it.
  3. 4. An electrical device that resists the flow of electrical current
  4. 7. A safety device with a thin metal strip that will melt if too much current passes through a circuit
  5. 8. A light source
  6. 9. An electrical power supply
