! THIS EDUCATIONAL PROJECT IS PART OF THE AUTHOR'S PROJECTS: https://rlomanov.kiev.ua ! LESSONS DEVELOPED USING S.T.E.M. TECHNOLOGY LESSON 2. SERIES AND PARALLEL CONNECTION OF CONDUCTORS. SHUNTS AND ADDITIONAL SUPPORTS BEGINNING OF THE LESSON. KNOWLEDGE UPDATE: Based on the material from previous lessons, recall and answer the questions: 1. What is electric current? What are the conditions for its occurrence and existence? 2. What devices are called sources of electric current? Give examples. 3. Reproduce how a galvanic cell; resistor; rheostat; ammeter; voltmeter; key are designated on electrical circuits. What are these devices intended for? 4. What is the direction of current in a circuit? 5. Give the characteristics of physical quantities: current strength in a circuit; voltage across a section of the circuit; conductor resistance; resistivity. 6. Formulate Ohm's law for a section of a circuit. WHAT PROBLEM QUESTIONS DOES THIS LESSON ANSWER: What types of conductor connections do you know? What are the main properties of these connections? LESSON OBJECTIVE: To consolidate and deepen knowledge about the patterns that exist in circuits with series and parallel connections of conductors; to familiarize yourself with methods for expanding the measurement limits of an ammeter and voltmeter; to form the ability to calculate the parameters of simple combined connections. INTERACTIVE DEMONSTRATIONS, SIMULATIONS AND EXPERIMENTS: Use interactive demonstrations for a deeper understanding of the lesson topic: https://phet.colorado.edu/sims/html/c... LESSON OUTLINE. PROBLEM SOLVING. PRACTICAL SKILLS REINFORCEMENT: Basic definitions and formulas. Additional text demonstration of detailed problem solving, additional problems: https://drive.google.com/file/d/1JItO... SUMMARY OF LESSON SUMMARY. CONSOLIDATION OF KNOWLEDGE: Based on the lesson material, answer the questions: 1. What connection of conductors is called series? 2. What relations hold true for series connection of conductors? Prove them. 3. What connection of conductors is called parallel? 4. What relations hold true for parallel connection of conductors? Prove them. 5. How can the upper limit of measurement of a voltmeter be increased? 6. In what case and how are ammeters shunted? HOMEWORK: Work out § 2, Exercise No. 2 (4, 5) Textbook: https://drive.google.com/file/d/1onYO... END OF LESSON
