Series & Parallel Circuit

Lesson Title: Series & Parallel Circuits

Grade Level: High school (10th-12th grade)

Subject: Applied Design, Skills, and Technology (ADST) Electronics. Also applicable for Science and Physics.

Duration: ~60 minutes

Required Equipment: Power Supply, Multimeter, Laptop with Wi-Fi access

Required Components: Breadboard, Resistors of varying values


  • Understand the fundamental differences between series and parallel circuits.

  • Analyze the behavior of current and voltage in both types of circuits.

  • Demonstrate the ability to set up series and parallel circuits on a breadboard.

  • Use the multimeter for taking measurements in these circuits.


Introduction (10 mins)

  • Introduce the concepts of series and parallel circuits and their significance.

  • Discuss the basic characteristics of each type, including how components are connected.

Simulation Activity (15 mins)

  • Guide students through a chosen simulation software/platform.

  • Set up a basic series circuit and a parallel circuit using virtual components.

  • Observe and note the behavior of current and voltage in both setups.

Hands-on Activity: Building Circuits (20 mins)

  • Demonstrate the setup of a series circuit on a breadboard using resistors and LEDs.

  • Proceed to show the setup for a parallel circuit.

  • Students recreate these circuits, observing the behavior of LEDs and noting the differences between the two setups.

  • Measure and discuss voltage drops across components in series circuits and current behavior in parallel circuits.

Using Measurement Tools (10 mins)

  • Guide students on using the multimeter to measure current and voltage in the circuits they've built.

  • Discuss the concepts of total resistance in series and parallel configurations.

Conclusion and Recap (5 mins)

  • Reiterate the key differences between series and parallel circuits and their real-world applications.

  • Engage students in a discussion about their observations and the practical implications of using each type of circuit.


  • Formative assessment: Throughout the lesson, students will be assessed on their engagement, participation in discussions, and ability to set up both types of circuits correctly.

  • Summative assessment: At the lesson's conclusion, students will take a written test covering the characteristics of series and parallel circuits, their advantages and disadvantages, and the behavior of current and voltage in each. Practical skills will be assessed through a hands-on test where students will be tasked with creating a specific circuit configuration.
