0

2)U=220B

I=0,1A

R= 220/ 0,1=2200 Ом

U2=2200 Ом * 0,05 =110B

Reading Task 2. Read the article about communication. What next for communication? by Jamie Rogers The way people communicate has changed a lot over the last few years. So many people have to check their social media page, Twitter account, emails or text messages every few minutes. How often do you see people in the street not paying any attention to what is going on around them? They are just busy ‘communicating’. For many people, these technological developments are exciting. Science fiction becomes science fact. What will the next big thing be? Imagine communicating with anyone, anywhere in the world through your glasses or your watch - well, you can now. Although these latest inventions are still expensive, they will become cheaper very soon. On the other hand, if people communicate through technology all the time, they might spend more time alone in isolation as a result. There may be no need to meet anyone face to face if you can listen to music, upload video clips, and send and receive text messages and emails through your watch at any time of the day or night. Although there are, of course, many benefits to the communication systems we have now, there is a danger that soon we will not be able to communicate in a real way. I hope that the advances in technology stop before we all have a microchip and end up being robots! Are the sentences True (T) or False (F)? Jamie Rogers tells us that 1. A lot of people use their mobile phones while walking. _____ 2. We aren’t able to communicate through our watches or glasses yet. _____ 3. The most recent inventions will not go down in price. _____ 4. In the future, people may spend less time with their friends. _____ 5. There are some good things about the ways we communicate now. _____ 6. There is no danger that soon we will not communicate in a real way _____ 7. He is worried we may all turn into a kind of machine.
