Circuits/Forms of Energy STAAR Bootcamp

When wires are connected to a battery and a lightbulb in a circuit, the lightbulb is lit. Which types of energy are produced by the battery and lightbulb?

• Electrical and light

• Sound and light

• Electrical and sound

• All of these

Students investigate the flow of electricity in circuits. The teacher instructs them to wear rubber gloves during the investigation because -

• rubber gloves are insulators

• rubber gloves are conductors

• rubber gloves keep the students dry

• rubber gloves allow electricity to flow

All of the bulbs in the circuit are lit.

What change would cause all of the bulbs to go out?

• Remove wires 3 and 4

• Remove wires 2 and 4

• Remove wires 3 and 2.

• Remove wires 3 and 5

What is wrong with this circuit?

• There are too many lightbulbs.

• The switch needs to be opened.

• The wires are not connected.

• Another energy source is needed.

A group of students makes observations while constructing circuits. Which of the following is an incorrect observation?

• The path for electricity to flow must be closed.

• Aluminum foil cannot be used as a path for electricity to flow.

• Conductors, such as copper wire and iron nails, can be used to connect the energy source to the lightbulb.
