• 2 light bulbs
• 1 ammeter
• 1 switch
• 1 battery
• 6 wires

• Figure 1 will last longer

32

• What are the advantages of a compound battery in
  parallel?

33

• Compound batteries in parallel will last longer.

34

• What are the advantages of a compound battery in
  series?

35

• Compound batteries in series will provide more
  power (the fan will spin faster and the light
  will be brighter).

36

• Which schematic(s) is a series circuit with a
  compound battery

• Build a circuit

53
Final Jeopardy

• Directions Draw a circuit with two batteries,
  three light bulbs, and two switches so that it
  has all the following components
• A master switch that turns the entire circuit on
  or off
• Two light bulbs remain lit when the third light
  bulb is taken out of its light socket
• A switch that will turn two light bulbs on or off
  at the same time, but will keep the third light
  on
