• A form of matter

• A type of sound wave

A closed circuit is needed for electricity to power our electronics because:

• It allows the flow of electric current.

• It prevents the flow of electric current.

• It stores electric charge.

• It blocks electric current.

What would be an advantage of a series circuit? Of a parallel circuit?

• Series circuits are easier to design and build.

• Parallel circuits allow devices to operate independently.

• Series circuits provide a consistent voltage across all components.

• Parallel circuits are more cost-effective.

What could you do to control the brightness of a light bulb or the spin of a motor in a circuit?

• Use a resistor

• Use a capacitor

• Use a switch

• Use a variable resistor

What are some advantages of using circuit boards in electronic devices?
