| Тілдік мақсаттар: | Subject-specific vocabulary & terminology electric current ampere (A) electric circuit open circuit closed circuit short circuit voltage volt (V) battery voltmeter Electromotive force (EMF) Terminal voltage Lost voltage Internal resistance Load resistance Useful set(s) of phrases for dialogue/writing All voltage sources have two fundamental parts: a source of electrical energy that has a characteristic electromotive force (emf), and an internal resistance r. The emf is the potential difference of a source when no current is flowing. The numerical value of the emf depends on the source of potential difference. The internal resistance r of a voltage source affects the output voltage when a current flows. The voltage output of a device is called its terminal voltage V and is given by V = emf − Ir, where I is the electric current and is positive when flowing away from the positive terminal of the voltage source. When multiple voltage sources are in series, their internal resistances add and their emfs add algebraically. |

Greeting I’m glad to see you. Brainstorming Before we start our lesson I want you to warm up.Ready? The task for you is very easy.you should repeat the actions and words after me. It’s time to think It’s time to speak It’s time to show Ready steady go. Now let’s do it a bit faster Today we are going to have a very interesting lesson. First of all let’s divide into 3 groups. Come here. Take the cards. Who takes ‘Аmper, that will be the group “Amper” and who takes ‘Volt’ that will be the group “Volt” and who takes ‘Om’ that will be the group “Om”. Now let’s elect the captain of the groups. I put a question to each group. Who answers the question that will be the captain of the group. Checking your homework using play game Kahoot (15 Questions) Ok, now let’s revise our previous lesson by doing True or false quiz in Bilimland.kz https://bilimland.uz/en/courses/physics-en/electrodynamics/electric-current/lesson/current-sources Descriptor: A learner - finds correct answers-1 FA: Knowledge passport | <p><a href="https://bilimland.uz/en/courses/physics-en/electrodynamics/electric-current/lesson/current-sources" target="_blank">https://bilimland.uz/en/courses/physics-en/electrodynamics/electric-current/lesson/current-sources</a></p><p>Worksheet# 1</p><p> Kahoot.it </p><p> Worksheet #2 </p><p><br></p> |

<p>The theme of our lesson is Ohm's law for the complete chain Now let’s write down new words of the lesson electric current, ampere (A), electric circuit, open circuit, closed circuit, short circuit, voltage, volt (V), battery, Electromotive force (EMF), тerminal voltage, lost voltage,internal resistance,load resistance,voltmeter Descriptor: A learner -- finds correct answers-1 “Stop frame” method After viewing the video, you need to create a poster in the group.Please, try do understand this text in book. https://bilimland.kz/en/courses/physics-en/electrodynamics/electric-current/lesson/electromotive-force You must understand and answer the following questions: What does a voltmeter measure when attached to a battery?</p><p>FA: if you have finished the work then clap your hands. Working in pairs and solving problems Task 1. Jobs on the cards. Descriptor: A learner - uses the Ohm's law formula for the complete chain Task 2. solve the problem by drawing Descriptor: A learner - uses instrument readings Individual work Task 3. to collect an electric battery, a key, three light bulbs, and a resistor using Ohm's law calculate the current in the circuit. Familiarize yourself with safety procedures. https://phet.colorado.edu/sims/html/circuit-construction-kit-dc-virtual-lab/latest/circuit-construction-kit-dc-virtual-lab_en.html </p> | <p><a href="https://bilimland.kz/en/courses/physics-en/electrodynamics/electric-current/lesson/electromotive-force" target="_blank">https://bilimland.kz/en/courses/physics-en/electrodynamics/electric-current/lesson/electromotive-force</a></p><p>slide </p><p> Worksheet# 3</p><p>Worksheet# 4 </p><p> Worksheet #5 </p><p>phet.colorado.edu </p><p> safety </p><p>https://phet.colorado.edu/sims/html/circuit-construction-kit-dc-virtual-lab/latest/circuit-construction-kit-dc-virtual-lab_en.html</p><p><br></p><p><br></p> |
