What is a situation where a  break in the circuit stops the flow of electrons. This condition causes the circuit to not work.

• Open circuit
• Break in the circuit
• Short circuit
• Parallel circuit

What is a situation where the “load” device is not in the circuit because something has directly connected the battery terminals together.

• Open circuit
• Ground fault
• Overload
• Short circuit

What is a device that has a designed resistance to the passage of current. Used to limit current flow in circuits.

• capacitor
• inductor
• diode
• resistor

What is a component that produces light (and heat) when current flows through it because of it’s resistance.

• fluorescent light bulb
• incandescent light bulb
• candle
• LED light bulb

What is a component that converts an electric signal to sound waves using a magnet.

• headphones
• speaker
• microphone
• amplifier

What is a component that uses electrical current and magnets to spin a shaft and create mechanical (kinetic) energy.

• generator
• electric motor
• battery
• solar panel
