• 
• 
• 
• 

What are the components of this circuit?

• 2 bulbs; 2 batteries; no switch

• 2 loads; closed switch; no source

• 2 loads; two batteries; open switch

What are parts of this circuit?

• 1 load; 1 power source; open switch

• 1 bulb; 1 battery; no switch

• 1 bulb; 1 battery; open switch

• 1 load; 1 power source; closed switch

Will the bulbs light up?

• YES

• NO

Why are metals good conductors of heat and electricity?

• They are gas materials.

• Their particles are slightly far from one another.

• They allow electrons to move freely through them.

Arrange the circuits from brightest to dimmest.

• A-B-C

• C-A-B

• A-C-B

• B-C-A

In which circuit will the bulbs shine brighter?

• 
• 

What type of circuit is shown?

• Series Circuit

• Parallel Circuit

Why does the bulb light up even if the other one is broken?

• One loop is still connected.

• It is a series circuit.

• The battery still works.

• There is only one pathway.
