Electricity IV

A student forgets to use a plastic coated wire and notices that the wire connecting to the battery is very hot. Which statement below explains why the wire is hot?

• The wire is not insulated and electrical energy from the wire produces heat.

• The wire is not insulated and electrical energy flowing from the battery produces heat

• The wire is not insulated and electrical energy from the bulb heats the wire.

• The wire is not insulated and electrical energy from the switch produces heat.

Which part of the circuit is the energy source?

• Wire

• Bulb

• Battery

• Switch

Which of these could NOT be used to replace a wire in a circuit?

• Iron Nail

• Bendable Straw

• Steel Spoon

• Aluminum Foil

Electricity can be used to produce -

• light

• heat

• sound

• all of the above

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

• electrical and light

• sound and light

• electrical and sound

• light and sound

Students were discovering how to create a circuit which lit a light bulb. The teacher recorded the work time for each group:

Which group took the least amount of time to complete their circuit?

• Group 1

• Group 2

• Group 3

• Group 4

Students were discovering how to create a circuit which lit a light bulb. The teacher recorded the work time for each group:

How much longer did it take Group 3 to light the bulb that Group 2?

• 55

• 35

• 25

• 20

Students made observations while constructing circuits. Which of the following would be 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 light bulb

• Electricity does not flow through the circuit when the circuit is open

Students were given materials to complete a circuit to turn on one light. The materials received were 2 wires, a AA battery, and various sizes of light bulbs. What is the variable in the experiment?

• Wires

• Battery

• Size of light bulb

• Time of day
