Electric Circuits

Max wants to fly a kite during a lightning storm at night. His friend warns him that this increases his chance of being struck by lightning. Which of the following helps to explain why this is true?

• Lightning usually strikes at night.

• Lightning usually strikes objects made of fabric.

• Lightning usually strikes moving objects.

• Lightning usually strikes objects high above the ground.

Mrs. Byars is building a simple circuit with a battery, light bulb, and copper wires. When she connects the wires to the battery terminals, the light bulb does not light up. Why doesn’t the bulb light up?

• Copper isn't a conductor.

• A battery can't make a light bulb shine.

• It isn't dark outside.

• The circuit is open.

Why would a string of outdoor lights be wired in a parallel circuit?

• As bulbs are added, the bulbs become dimmer.

• If one bulb goes out, the circuit stays closed.

• There is one path in which the electric charges flow.
