SPS10ab Lesson Review Quiz

The energy source that pushes electrons through conductive wires

(a)  

What is the current in amperes?

What type of circuit is this?

• 9 amps

• 3 amps

• Parallel Circuit

• Series Circuit

The diagram below shows three light bulbs connected in a parallel circuit with an open switch. Which light bulb will be turned off by the opened switch?

• Lightbulb 1

• Lightbulb 2

• Lightbulb 3

• No lightbulbs would be affected

What are the two factors that affect the rate of current flow?

• Voltage

• Circuit

• Current

• Resistance

Marty made a list about series circuits.

Series Circuits

• The current has only one path to take.

• An example is a simple flashlight.

• The current is different in every resistor.

• The total resistance is the sum of the resistor values.

Marty made a mistake in his list. What mistake did he make?

• The current can take multiple paths.

• The simple flashlight is not an example.
  

• The current is the same in every resistor.

• The total resistance is the mean resistor value.

Which circuit will stop producing light if one lightbulb goes out?

• Circuit 1

• Circuit 2

• Circuit 3

• Circuit 4

(a)   circuits have multiple pathways.

How does the current change for each test?

• It increases.

• It decreases.

• It stays the same.

• The current stops.

Which statement BEST describes the relationship between current, voltage, and resistance during this investigation?

• The current decreases as the voltage increases when resistance remains the same.

• The voltage decreases as the resistance increases when the current remains the same.

• The current increases as the voltage increases when resistance remains the same.

• The voltage increases as the resistance decreases when the current remains the same.

There are 3.0 amps of current flowing through a 12 volt battery in a circuit. How many amps will flow through the circuit if the resistance in the circuit is reduced by half?

• 1.5 amps

• 3.0 amps

• 6.0 amps

• 12.0 amps
