Watch your students finally "get" parallel circuits as they work through this classroom-tested slide deck that turns abstract concepts into concrete understanding. No more blank stares when you mention current splitting or resistance calculations.
What's Included:
- ✓ Ready-to-use PowerPoint with 30+ slides covering all parallel circuit fundamentals
- ✓ Step-by-step resistance calculation examples with visual diagrams
- ✓ Interactive discussion prompts to spark critical thinking
- ✓ Real-world applications students actually recognize (house wiring, car lights)
- ✓ Editable format - customize for your teaching style
- ✓ NGSS HS-PS3-3 alignment built right in
Why Teachers Love This:
- Students grasp why adding resistors decreases total resistance (the counterintuitive concept that trips everyone up)
- Clear visual progression from simple parallel branches to complex circuit analysis
- Discussion questions that reveal student misconceptions before they become test mistakes
- No prep time needed - just open and teach
Perfect For:
- High school physics (grades 9-12)
- Conceptual physics courses
- Honors physics circuit units
- Teachers introducing parallel circuits or reviewing before assessments
Pro Tip: Use the brightness comparison slides to help students predict circuit behavior before calculating - it builds their physics intuition.

How our resources align to NGSS. Every Phantastic Physics resource is built for the NGSS high school physical science performance expectations. The specific standard each resource targets is listed in its product description. The reference below shows how our eight units map to the standards.
Unit 1 — Motion
The NGSS high school standards contain no stand-alone kinematics performance expectation. Our Motion unit builds the graphing, data-analysis, and mathematical-representation skills students need for HS-PS2-1 and the other force and motion standards.
Unit 2 — Forces
HS-PS2-1 — Analyze data to support the claim that Newton's second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.
Unit 3 — Momentum
HS-PS2-2 — Use mathematical representations to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system.
HS-PS2-3 — Apply scientific and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.
Unit 4 — Gravity
HS-PS2-4 — Use mathematical representations of Newton's Law of Gravitation and Coulomb's Law to describe and predict the gravitational and electrostatic forces between objects.
HS-ESS1-4 — Use mathematical or computational representations to predict the motion of orbiting objects in the solar system.
Unit 5 — Static Electricity
HS-PS2-4 — Use mathematical representations of Newton's Law of Gravitation and Coulomb's Law to describe and predict the gravitational and electrostatic forces between objects.
HS-PS3-5 — Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction.
Unit 6 — Energy
HS-PS3-1 — Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.
HS-PS3-2 — Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motion of particles (objects) and energy associated with the relative position of particles (objects).
HS-PS3-3 — Design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy.
Unit 7 — Electric Circuits
HS-PS3-1 — Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.
HS-PS3-3 — Design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy.
Unit 8 — Waves
HS-PS4-1 — Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.
HS-PS4-3 — Evaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described either by a wave model or a particle model, and that for some situations one model is more useful than the other.
HS-PS4-5 — Communicate technical information about how some technological devices use the principles of wave behavior and wave interactions with matter to transmit and capture information and energy.
