Science 5.6b

Front

A student builds a circuit made up of a battery, two light bulbs, and a switch. What will the student most likely observe in this circuit?

Back

Light bulb 1 will be on, but light bulb 2 will be off

Front

The diagram shows a series circuit with three lit bulbs. How many of the bulbs will remain lit if the wire is cut at the point shown by the arrow?

Back

0

Front

Which change to the electric circuit will cause the lightbulb to light up? Options: Straightening the wire, Adding a switch and more wire, Turning one battery so that its positive end connects to the other battery's negative end, Making the length of wire the same on both sides of the lightbulb.

Back

Turning one battery so that its positive end connects to the other battery's negative end.

Front

A string of lights with small bulbs is shown below. The bulbs are connected by wire that is covered in an insulator. When the lights are on, electricity travels in...

Back

a complete circuit

Front

Why are there two metal posts on a battery used to connect to a bell and a switch?

Back

The battery needs to form a complete circuit that starts with one metal post and ends with the other metal post.

Front

What happens if the wire in a car fuse burns out?

Back

The car's radio will not work

Front

Why does the lightbulb not glow in the circuit? Options: The battery is not charged, The lightbulb is not part of a complete circuit, The circuit does not have a switch, The bell uses most of the energy from the battery.

Back

The lightbulb is not part of a complete circuit

Front

In addition to mechanical energy, what is produced as electric current passes through the circuit of an electric fan?

Back

Heat

Front

To recharge the battery for later use without lighting the bulb, which switches should be closed?

Back

switches R and T only

Front

All the lightbulbs in this circuit are lit. Which change would cause all the bulbs to go out? Options: Removing wire 1, Removing wires 2 and 4, Removing wires 2 and 5, Removing wires 3 and 4

Back

Removing wire 1
