Unit 3 Finale

A class prepared some electrical circuits using battery, connecting wires, and three light bulbs.  Which of these circuits can make the three bulbs light?

• A
• B
• C
• D

The diagram shows a series circuit with three lit bulbs. How many of the bulbs will remain lit if the wire is cut a the point shown by the arrow?

• 0

• 1

• 2

• 3

Describe a series circuit.

• a circuit that has multiple branches

• a circuit that has one path

• a circuit that dead ends after a light bulb

What is a parallel circuit?

• a continuous loop

• a circuit with one path

• a circuit with multiple branches for each individual appliance or light

an electric circuit with only one branch

• series circuit

• parallel circuit

• open circuit

• closed circuit

This is the symbol for a(n) ..................?

• single cell

• bulb

• battery

• AC current source

This is the symbol for a ..................?

• single cell

• bulb

• battery

• switch

Which is a unit of electrical force shown on a battery?

• Amps

• Series

• Volts

• Joules

The total resistance in this circuit is 

• 100 ohms
• 450 ohms
• 400 ohms
• 30 ohms

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
