Combination Circuits

In this topic, you will learn how to calculate currents and voltages in a complicated circuit like the one shown below. Download a printable version of this warm-up activity.

This circuit has five identical resistors, each resistor is a 1 Ω resistor.  The battery has 6 V.

For this circuit, answer the following questions:

1. Which two resistors have the same current?

2. Which resistor has the most current?

3. Which resistor has the least current?

4. Which resistor, if removed, would stop the current flow in the circuit?

Now, check your answers to see how you did.
