Закон Ома

>Do you know the famous physics scientists?
I want to make you know the portraits of some great scientists of the world. Here are some pictures. Look at it, please.
This is a portrait of Andrew Ampere. What is the Russian for Andrew Ampere? What is his nationality? What did he invent?
This is a portrait of Isaac Newton. What is the Russian for Isaac Newton? Where did he live? What did he invent?

- Who knows the "Ohms Law"? Write its formulas on the blackboard and the other students write in their copy - books.
4. От каждой группы по одному представителю рассказывают закон Ома и записывают его формулы.
Ohms Law
R V/I resistance equals voltage divided by current
I V/R current equals voltage divided by resistance
V IR voltage equals current times resistance

Решение задач (Учитель диктует условия задач на английском языке, ученики записывают на слух в группах, по одному представителю от каждой группы записывают решение и результаты на доске).
Student 1, go to the black board and write the task. The others help him to do it correctly. Its task is for your group. Do the task all together, choose one student from your group, who will write the tasks result.
Task: Current equals 5 amp, resistance equals 10 ohms. How muc
