- OGS.12.PS3.1Apply the principle of conservation of electric charge during friction, conduction, induction, and polarization; calculate electrostatic forces using Coulomb's law and determine electric field intensity vectors and potential for point, spherical, and planar charge distributions.
- OGS.12.PS3.2Analyze parallel-plate capacitors, dielectric materials, and capacitance: calculate stored electrical energy, dielectric polarization effects, and exponential transient charge and discharge voltage-time curves.
- OGS.12.PS3.3Investigate electric current, electromotive force (EMF), internal resistance, and electrical resistivity in ohmic and non-ohmic conductors; analyze temperature dependence of resistance in metals versus semiconductors.
- OGS.12.PS3.4Design, construct, and solve series, parallel, and complex DC circuits using Kirchhoff's Junction (charge conservation) and Loop (energy conservation) laws, potential divider equations, and Joule heating power dissipation formulas.
- OGS.12.PS3.5Evaluate domestic electrical infrastructure, alternating current (AC) root-mean-square parameters, semiconductor components (diodes, rectifiers, transistors, LDRs, thermistors), electrical power safety devices (fuses, residual-current circuit breakers, grounding), and high-voltage grid transmission.
- OGS.12.PS3.6Investigate magnetic fields generated by permanent magnets, straight current conductors, and solenoids; calculate magnetic force on current-carrying wires (F = BIL) and moving charged particles (Lorentz force F = qvB sin θ), explaining the operation of DC electric motors and Earth's magnetosphere.
- OGS.12.PS3.7Model electromagnetic induction: apply Faraday's and Lenz's laws to calculate induced EMF from rates of magnetic flux linkage change; explain the principles of electrical generators, self-induction, ideal step-up/step-down transformers, and Maxwellian electromagnetic wave propagation.
