### Understanding the Ammeter and Series Circuits

**What is an Ammeter?**

An ammeter is a tool designed to measure the electric current (technically referred to as an "ampmeter") that flows through a circuit. In this simulation, ammeters can be accessed from the toolbar located in the upper right corner.

**How to Use an Ammeter:**

When current flows through the meter, a numerical value will appear, replacing the question mark initially displayed on the ammeter.

![Toolbar screenshot with options to show current, electrons, conventional flow, labels, and values. There are icons for a voltmeter, ammeter, and a wire resistivity option.]

**Building and Testing a Series Circuit:**

1. **Construct the Circuit:**
   - Assemble a simple series circuit using a battery, switch, single light bulb, and ammeter, as depicted in the image.

   - *Note:* The switch isn't strictly necessary, but it helps prevent the image from revealing the answers.

2. **Measure the Current:**
   - With the switch closed (allowing current to flow), observe and record the current flowing from the light bulb back to the battery.

   - **Enter Measurement:** The current is ______ A.

   ![Diagram of a circuit with a battery, switch, and a light bulb. The ammeter shows a current of 0.00 A.]

3. **Reconfigure and Measure Again:**
   - Rearrange the circuit by switching the positions of the light bulb and the battery, ensuring the ammeter is placed before the bulb.

   - Again, with the switch closed and current flowing, record the current exiting the battery and entering the light bulb.

   - **Enter Measurement:** The current is ______ A.

   ![Diagram of a circuit with a reconfigured setup showing the ammeter before the light bulb. The ammeter shows a current of 0.00 A.]
