Exploring Series and Parallel Circuits

The video tutorial explains the differences between series and parallel circuits. In a series circuit, all bulbs are connected in a single path, increasing resistance and reducing current and brightness as more bulbs are added. If one bulb's filament breaks, the entire circuit is disrupted. In contrast, a parallel circuit connects bulbs across multiple branches, allowing each branch to function independently, maintaining brightness even if one bulb fails.

What are the two main ways to connect bulbs in a circuit?

• Series and Parallel

• Direct and Indirect

• Single and Multiple

• Open and Closed

In a series circuit, what happens to the resistance when more bulbs are added?

• It decreases

• It increases

• It fluctuates

• It remains the same

What is the effect on the brightness of bulbs in a series circuit when the resistance increases?

• Brightness fluctuates

• Brightness remains the same

• Brightness decreases

• Brightness increases

What happens to the entire series circuit if the filament of one bulb breaks?

• Only the broken bulb goes out

• None of the bulbs will light up

• All bulbs remain lit

• The circuit remains unaffected

In a parallel circuit, how are the bulbs connected?

• In a single path

• In two or more branches

• In a zigzag pattern

• In a loop
