7. Translate the following sentences into English.
1. Резистори застосовуються в схемах електротехніки та електроніки для обмеження сили струму та розподілу напруги.
2. Конденсатор у колі постійної напруги не проводить струм, оскільки його обкладки розділені діелектриком.
3. У ланцюгу зі змінною напругою він проводить електричний струм, оскільки коливання змінного струму викликають циклічну перезарядку конденсатора, а тому і струм у ланцюгу.
4. У ланцюгу зі змінною напругою він проводить електричний струм, оскільки коливання змінного струму викликають циклічну перезарядку конденсатора, а тому і струм у ланцюгу.
5. Щоб струм через провідник був тривалим, цей провідник має бути замкнутим. У протилежному випадку заряди нагромаджуватимуться на кінцях провідника, відштовхуватимуть наступні однойменно заряджені частинки і струм припиниться.
6. Електрична енергія від джерела струму передається по проводах споживачам: електродвигунам, лампам, нагрівальним приладам, телевізорам, радіоприймачам тощо.
7. За допомогою з’єднувальних провідників і вимикачів в електричне коло часто вмикають також вимірювальні прилади: амперметри, вольтметри, омметри, лічильники електричної енергії тощо.
8. При послідовному з’єднанні споживачів вихід з ладу одного з них веде до розмикання кола.
Listening.
Listen to the explanation of Michael Horton, the science coordinator at the Riverside County Office of Education in Southern California about Christmas lights which are wired in parallel and mark the following statements are true or false:
1. Christmas lights are wired as a standard circuit 2. A glass ball acts as conductor 3. The filament is a coil of wire that heats up and glows when electricity passes through it 4. If the filament burns out, current won’t pass through that wire. 5. If three or more bulbs burn out, that string of 50 will stop glowing. 6. Bulbs are usually colored green on the tip to identify them. |
True / False True / False True / False
True / False True / False True / False |
Listen again and complete the sentences below.
1. In a ____________ circuit, if one element burns out and the rest of the circuit keeps working, this is a strong ____________ that the circuit is wired in parallel.
2. If you look at the inner-workings of the ____________, you will see several major ____________.
3. The two metal supports hold the _________ and connect it to the base where the electrical contact is made.
4. The thin wire has higher ________ than the filament, so little ___________ flows through it normally.
5. If more than a ____________ of filaments burn out, the higher resistance causes the light string to fail. 6. Each ____________ bulb draws ____________volts and your home electricity is 120 volts.
7. Circuits of 50 bulbs are ____________ in series.
8. If you ____________ a string of 20 bulbs, then those are not 2.5 ____________ bulbs.
9. There is a special bulb that can be put into a strong that will make the string of lights ____________. 10. When it ____________, it no longer touches the support and breaks the circuit.
Speaking. Look at each circuit diagram below.
a) Do you think the bulb(s) will light? If you do, put a tick in BOX A under the diagram. If not, put a cross. b) Now make the circuit using the equipment. Does the bulb light? If it does, put a tick in BOX B. If not, put a cross. c) Repeat this for all of the circuit diagrams. Then compare your predictions (BOX A) to your results (BOX B) and share your findings with a partner.
