Electricity and circuits

What type of circuit is shown in the image?

• Parallel Circuit

• Series Circuit

• Magnetic Circuit

The path that electricity travels through is called

• a circuit

• voltage

• current

• resistance

What happens to the brightness of the light bulbs when you add more bulbs to a series circuit?

• The brightness stays the same.

• The bulbs get brighter

• The bulbs get dimmer

Where do the leads (black and red wires) need to be placed to correctly read the current of the circuit?

• Place the leads on each side of the open switch.

• Place the leads on each side of the closed switch.

• Place the leads on each side of the battery

• Place the leads on each side of the light bulb

• Place the leads at any two corners of the circuit.

What happens to the brightness of the light bulbs when you add more bulbs to a parallel circuit?

• The brightness stays the same.

• The bulbs get brighter

• The bulbs get dimmer

What happens to the current when you add more bulbs into a parallel circuit?

• The current stays the same.

• The current slows down (flows more slowly).

• The current speeds up (flows faster).

What happens to the bulbs when you disconnect one bulb in a parallel circuit?

• All the bulbs go out because you stopped the current from flowing.

• There is no change to the circuit.

• The other bulbs will stay on because they each have their own circuit (current pathway).
