  • Name & describe this.
    Series circuit. Components connected one after another in series.

  • Name & describe this
    Parallel circuits. They have components connected in parallel, on their own branches.

  • Name this device that measures current.
    Ammeter

  • Name this instrument that is used to measure the amount of energy released by electrons (volts)
    Voltmeter

  • The problem with circuit series.
    If one of the components breaks, the whole circuit is broken and the current stops.

  • Parallel or series circuit? The current in each branch is the same but add together to make the total current of the circuit.
    Parallel
  •  10
  • Parallel or series circuit? The current is the same everywhere.

  • If the first ammeter in this series read 3 amps? What would the other 2 read? If I added another component would they change?
    3, yes-they would all lower.
  •  10
  • In relation to the readings on the ammeters-True or False? A2 + A3 = A1 A1 = A4
    True

  • The amount of charge per second is called a....
    Current

  • A battery produces a charge-True or False
    False-The charge already exists and the battery just pushes it.
