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.

What is the total resistance (RT) across this circuit?

• 3 kΩ

• 10 kΩ

• 13 kΩ

• 18 kΩ

As resistors are added in series to a circuit, the total resistance will...

• increase
• decrease
• stay the same

As the resistance of a circuit increases, the current will...

• increase
• decrease
• stay the same

In a parallel circuit which of the following is the same value throughout the circuit?

• Voltage
• Current
• Resistance
• Charge

Does this diagram represent a series or parallel circuit?

• series circuit
• parallel circuit

What is the definition of electrical current?

• The opposition to the flow of electrons

• The rate of flow of charge

• The work done on each coulomb of charge

• Electrons moving around

This is an example of a ______ circuit

• Series
• Parallel
• Open
• Dihexihedral

This circuit has more than one loop. When one light goes out, the others stay on. 

• closed circuit
• series circuit
• parallel circuit
• open circuit

• all bulbs are lit equally
• the two top bulbs are brighter
• the single lower bulb is brighter
• the single bulb does not light and the other two are dim
