NGSS.4-PS3-2

In an open circuit, a light bulb would

• Still glow because the wires can repel electricity

• Remain switched off because there is a gap in the circuit

• Remain switched off unless the voltage on a power pack was turned up to the maximum

• Fracture due to the pressure of the electricity in the wires

What is electricity?

• flow of water

• flow of air

• flow of atoms

• flow of electrons
