Understanding Electricity and Circuit Brightness

What is the main topic discussed by Kenneth in the video?

• Photosynthesis

• Electricity and bulb brightness

• Magnetism

• The water cycle

How do you determine the order of brightness in circuits?

• By measuring the length of the circuit

• By counting the number of wires

• By checking the color of the bulbs

• By finding the ratio of bulbs to batteries

What is the ratio of bulbs to batteries in Circuit A?

• 1:1.5

• 1:2/3

• 1:1

• 1:2

Which circuit has the highest ratio of bulbs to batteries?

• Circuit A

• Circuit B

• Circuit C

• All circuits have the same ratio
