What is a design brief? (Pick two)

• A statement that outlines what problem the design will solve

• A plan that breaks down each area to provide detail to the problem being solved.

• A short concise sentence

• A detailed table, discussing ACCESS FM

What is a design specification? (Pick two)

• A statement that outlines what problem the design will solve

• A plan that breaks down each area to provide detail to the problem being solved.

• A short concise sentence

• A detailed table, discussing ACCESS FM

Why is copper using inside a speaker? (Pick two)

• Copper is non-magnetic, so is therefore not attracted to the permanent magnet in the speaker.

• Copper is not conductive which means that the current cannot pass through it.

• Copper is magnetic which allows it be attracted to either the north or south magnet.

• It is highly conductive which creates an electromagnet when current is passed through the copper coil.

How does a speaker work?

• Current is passed through the copper coil to create an electromagnet, which moves the diaphragm creating sound waves.

• Current is passed around the copper coil to create an electromagnet, which moves the diaphragm creating sound waves.

• The cone moves back and forwards creating sound waves

• The copper controls the cone by making it move.

Why is it important for a speaker to be enclosed?

• To make it look pretty

• To protect it

• To prevent the sound from travelling backwards and the sound becoming muffled.

• To keep it safe

What does a resistor do?

• It slows the flow of electricity running through a circuit.

• It is an energy storage device that smooths out the power

What does a capacitor do?

• It slows the flow of electricity running through a circuit.

• It is an energy storage device that smooths out the power

The colours of the resistor are red, blue, yellow, gold - calculate the ohms
