A cell or battery stores electrical energy and pushes current around the circuit.

Which part of a circuit lets you open or close the current's path?

• Switch
• Battery
• Insulator

What word describes the push that moves current through a circuit?

• Resistance
• Voltage
• Component

Which pair correctly matches a term with its meaning?

• Resistance: how hard it is for current to flow
• Current: the electrical push in a circuit
• Insulator: a material that lets current flow easily

In a series circuit, one bulb burns out. What happens to the rest of the circuit?

• The other bulbs stay lit, because current finds another path
• Nothing changes, because the battery keeps working
• The other bulbs go out too, because there's only one path

Count the components in this circuit loop. Type how many there are.

A circuit has high resistance. What effect does this most likely have on the current?

• The voltage disappears completely
• The current gets bigger
• The current gets smaller

Maya wires two bulbs so each bulb has its own separate path back to the battery. She calls it a series circuit. What's her mistake?

• She actually built an insulator, not a circuit
• She actually built a parallel circuit, since each bulb has its own path
• She actually measured resistance instead of building a circuit
