As you continue to add lightbulbs in series, what happens?
The bulbs get brighter
The bulbs get dimmer
The bulbs remain the same brightness
The bulbs explode and shards of glass get everywhere
The picture shows an electrical circuit. This circuit is a series circuit because:
It has 3 light bulbs.
The same current flows through all three light bulbs.
It uses a single battery.
The electrical current is divided between the three light bulbs.
The voltage of the entire circuit is 18V. What is the voltage of Lamp B
18V
3V
9V
6V
