Using what you know about requirements for a functioning circuit, will C make the bulb light up?

• Yes

• No

Answer explanation

The circuit is complete but electrons have no way to flow to the negative terminal of the battery

Using what you know about requirements for a functioning circuit, will D make the bulb light up?

• Yes

• No

Answer explanation

The circuit is complete and electrons may flow from negative to positive (through the lightbulb)

Using what you know about requirements for a functioning circuit, will E make the bulb light up?

• Yes

• No

Answer explanation

Although the circuit appears complete, both wires are touching where they contact the bulb, so they would bypass the light!

Using what you know about requirements for a functioning circuit, will G make the bulb light up?

• Yes

• No

Answer explanation

The circuit is complete and electrons may flow from negative to positive. Metal paper clips are conductors so would not impede the flow of electrons... merely become part of the circuit!

Using what you know about requirements for a functioning circuit, will H make the bulb light up?

• Yes

• No

Answer explanation

The circuit is complete but an eraser is an insulator so impedes the flow of electrons so they cannot get past!

Using what you know about requirements for a functioning circuit, why is the configuration in I a bad idea?

• The electrons would not be able to flow from positive to negative

• The wire or battery would get extremely hot because there is no resistance in the circuit

• Electrons cannot flow without a lightbulb being connected in the circuit

• That's just how it is. There's no rhyme or reason, sorry!

Answer explanation

Flowing electrons produce energy. This results in the wire and battery getting very hot, possibly causing burns and fires!
