DOL 3/19

The diagram below shows a bulb and a wire attached to a battery. Why would this bulb be lit?

• The wire is wrapped to the bottom of the bulb that is a type of conductor.

• The wire is wrapped to the battery and that is why the bulb is glowing.

• The wire is wrapped to the glass and the glass is an insulator causing the light to grow

• The wire is wrapped to the bottom of the bulb with a metal case, a conductor which is touching the battery causing the light bulb to glow.

A group of students are building a circuit. The investigation is shown below. Which of the following statements correctly explains why the circuit is open?

• The bulb needs to be replaced in order to make it a closed circuit

• Switching one of the batteries so that the positive end connects to the other battery.

• The wires need to be attached to the battery not the battery holder

• Adding new batteries so that the electric current can flow through the wires.

Observe the circuit below. If the students connect a wire between bell 2 and bell 4, which of the bells will ring?

• Bells 1 and 3

• Bells 1 and 4

• Bells 1, 2, and 4

• Bells 1, 3, and 4
