Electrical Engineering – Электротехника

- What is electrical engineering?
- What products do electrical engineers make?
Electrical engineering is one of the newer branches of engineering, and dates back to the late 19th century. It is the branch of engineering that deals with the technology of electricity. Electrical engineers work on a wide range of components, devices and systems, from tiny microchips to huge power station generators.
What does an Electrical Engineer do? Electrical engineers work on a variety of projects, such as computers, robots, cell phones, cards, radars, navigation systems, wiring and lighting in buildings and other kinds of electrical systems.

From: Ted Everett
To: Brian Smith
Subject: Deadline changes
Brian,
The deadline for the model GR-7 DVD player project in next month. As a result, we’re delaying production on the GR-2.2 model. We need to adjust our production of some components.
Fortunately, both models use many of the same part. Keep making circuit card assemblies for both. However, the models use the different power supplies. Stop all production of GR-2.2 power supplies and focus on creating GR-7 power supplies.
Remember to make the necessary adjustments. The GR-7 power supplies require an input voltage of 120 volts and an output voltage of 5 volts. These are slightly higher than the settings for the GR-2.2 power supplies. Remember the output power, too. The GR-7 power supplies must produce 27 watts – the GR-2.2 only produce 24 watts.
Please inform the rest of the staff of the change.
Ted Everett
Electrical Engineering Supervisor

Which of the following is NOT true?
a) The GR-2.2 and GR-7 use the same power supply
b) The circuit card assemblies can be used in both models
c) The GR-2.2 has a lower input voltage than the GR-7
d) The GR-7 has a greater output power than the GR-2.2
What can you infer about the company?
a) It has over 120 employees
b) Its DVD players have incorrect output voltages
c) It has different deadlines for the different models
d) It purchases power sources from manufactures

Listen again and complete the conversation
Manager: Valerie, can I talk to you for a moment
Engineer: Of course, Mr. Smith. What’s up?
Manager: We’re changing the deadlines on the GR-7 and GR-2.2 DVD player projects
Engineer: Really? Aren’t we trying to finish both at the same time?
Manager: The GR-7 models are due next month. So we’re pushing back GR-2.2s
Engineer: Okay. I’ll stop production on all GR-2.2 components
Manager: No, don’t do that. The same circuit card assemblies work in both products.
Engineer: Oh, that’s right. We just need to hold off on GR-2.2 power supply then.
Listen to a conversation between a manager and an engineer. Mark the following statements as true (T) or false(F).
The man decides not to change the deadline
The company will stop production of all GR-2.2 parts
The woman is creating a new power supply.
