Electric Current & Voltage Phenomena-Based Lesson: Minimizing Ohmic Resistance Heating Losses Across Continental Distances Using Megavolt Ultra-High-Voltage DC Supergrids Presentation | Academic Physics | Grades 9–12

This is the student-facing slide presentation that introduces the phenomenon, walks the class through observations and driving questions, and frames the evidence students will use for the Phenomena-Based Lesson in the Academic Physics (grades 9–12) chapter Electric Current & Voltage, built around the phenomenon Minimizing Ohmic Resistance Heating Losses Across Continental Distances Using Megavolt Ultra-High-Voltage DC Supergrids. It is sold separately from the other two parts of the set.

• What's inside: Student Slide Show (editable .pptx + PDF, 22 slides).
• Resource type: Phenomena-Based Lesson – Presentation. Format: editable Microsoft PowerPoint file plus a ready-to-print PDF.

Classroom use: Open with the phenomenon slide show, let students record ideas on the response sheet, and lead the discussion with the teacher guide. Built for Academic Physics, grades 9–12.

Sample question“How does boosting voltage to extreme levels allow electric current to carry immense energy across a continent while generating almost no heat in the wire?”
