Use the following diagram for the next three questions.
What is the equivalent (total) resistance of the circuit? *
1 point
What is the current flowing near the battery? *
1 point
What is the voltage drop across the 3 ohm resistor? *
1 point
Use the following diagrams to answer the next two questions. All resistors are identical and the battery voltages are shown. The ground symbol means that the wire at that point has a potential of zero.
Which circuit has the highest current flowing through the point at the upper right hand corner? *
1 point
Which circuit has the lowest potential value at the the upper right hand corner? Remember that the ground symbol establishes where the potential has a value of zero. *
