Circuits Experiment Quiz

What is the first step in setting up the simple circuit in the experiment?

• Tape the wire to the negative end of the battery.

• Attach the wire to the bulb holder.

• Screw in the bulb.

• Connect the wire to the positive end of the battery.

What happens to the brightness of the bulbs when a second bulb is added to the circuit?

• The brightness remains the same.

• The bulbs become dimmer.

• The bulbs do not light up.

• The bulbs become brighter.

How does adding a second battery affect the brightness of the bulbs?

• The bulbs become dimmer.

• The bulbs become brighter.

• The brightness remains unchanged.

• The bulbs turn off.

In a parallel circuit, what happens when one bulb is unscrewed?

• The other bulb turns off.

• The other bulb remains on.

• The circuit breaks completely.

• Both bulbs turn off.

What is one advantage of using a parallel circuit over a series circuit?

• It uses more energy.

• It requires more components.

• It allows the circuit to function even if one bulb fails.

• It makes the bulbs dimmer.
