Circuits Quiz

The batteries and bulbs of the two circuits shown below are identical. In which circuit will there be the greatest

resistance?

• 
• 
• The resistance will be the same in both circuits.

• More information is needed to answer the question.

Consider the diagram of a 2-cell, 3-bulb circuit at the left. Several positions in the circuit are labeled with a letter. At which two positions is the voltage the same?

• A and H

• B and D

• E and F

• F and G

A 2-battery, 2-bulb circuit is shown in the diagram. The two light bulbs are identical. Several points are labeled around the circuit. How do the currents at point B and point D compare?

• The current is greatest at point B.

• The current is greatest at point D.

• The current is the same at points B and D.

• The current cannot be compared.

Which circuit has the smallest equivalent (total) resistance?

• 
• 
• 
• 

Which one of the following circuits has the largest resistance?

• 
• 
• 
• 

In this circuit, what is the current through the 2-ohm

resistor?

• 0.2 A

• 0.8 A

• 5.0 A

• 8.0 A

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 has more than one path to flow through

If the cell in the circuit above has a potential difference of 8V, what is the potential difference across one of the bulbs?

• 8V

• 4V

• 16V

• 2V
