Some students constructed a battery–powered circuit like the one in the picture above. Which of the following BEST explains why the light bulb would not light up?

• The circuit requires a different type of battery

• The circuit needs more power than is available.

• The switch in the circuit is missing

• The wires are connected incorrectly to the battery.

A student constructed a circuit using copper wires, a 6-volt battery, a light bulb, and a switch. Which of these is the source of energy for the circuit?

• copper wires

• battery

• light bulb

• switch

A circuit is constructed using a 6-volt battery, copper wires, and a bell. Another circuit is constructed using a 9-volt battery, string, and a bell. The first circuit produced a sound. Which of the following MOST LIKELY explains why the other circuit did not produce a sound?

• The battery produced more power than needed.

• The wires were lacking proper insulation.

• The bell was designed to produce little sound.

• The string is a poor conductor of electricity.

A student builds the circuit shown in the figure. In this circuit, the bulb does not light up. Which change should the student make to light the bulb?

• replace the battery

• change where the wires touch the battery

• replace the light bulb

• replace the light bulb
