Electric Energy: The Electric Lamps

The video tutorial explains the basic concepts of connecting light bulbs in a circuit. It introduces the initial circuit diagram and explores two methods of connecting a second light bulb: in series and in parallel. In a series connection, the bulbs share a common terminal, and the current is the same through both. If one bulb fails, the circuit is broken. In a parallel connection, each bulb has its own path, allowing one to remain lit if the other fails.

What happens to the current flow when two light bulbs are connected in series?

• The current splits between the bulbs.

• The current stops completely.

• The current flows through both bulbs equally.

• The current bypasses the bulbs.

In a series connection, what occurs if one light bulb's filament breaks?

• The current is redirected to another path.

• The other bulb continues to glow.

• The current increases in the other bulb.

• The entire branch stops conducting current.

How are light bulbs connected in parallel different from those in series?

• They share the same current.

• They require more power.

• They have different current paths.

• They cannot function independently.

What is the effect on the other bulb if one bulb in a parallel connection is faulty?

• The other bulb turns off.

• The other bulb continues to light up.

• The other bulb flickers.

• The other bulb dims.

Which of the following is true about parallel connections?

• They require all components to work for the circuit to function.

• They allow for different currents in each branch.

• They have a single path for current.

• They are less reliable than series connections.
