About the Lesson

This lesson simulates a simple series circuit.
As a result, students will:

• Identify and use components of the circuit.
• Set values for source voltage and resistances.
• Connect a voltmeter properly to measure voltages across resistors.
• Use data to develop Ohm’s Law.
• Apply circuit knowledge and Ohm’s Law to sketch and calculate current flow.
