1. The Resistor - резистор. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors act to reduce current flow, and, at the same time, act to lower voltage levels within circuits. In electronic circuits, resistors are used to limit current flow, to adjust signal levels, bias active elements, and terminate transmission lines among other uses.

2. Insulating material - изолирующий материал. The main energy-saving methods become insulating materials. The manufacturing technology of such products can insulate and maintain a temperature without harm to others. For events in isolation, you can save more than 40% of energy and to protect against corrosion of metal piping.

3. Insulating layer - изолирующий слой. The layer provides the necessary thermal performance of the multilayered pipe structure.

4. А parallel plate capacitor - конденсатор с параллельными пластинами. The simple type of capacitor is a flat capacitor with parallel plates, made of two parallel sheets of metal separated by an insulator (called the dielectric), and one of the plates is grounded.

5. The capacitor dielectric - конденсаторный диэлектрик. Commercially manufactured capacitors typically use a solid dielectric material with high permittivity as the intervening medium between the stored positive and negative charges.

6. Static Voltage - статическое напряжение. Voltage, otherwise known as electrical potential difference or electric tension is the difference in electric potential between two points — or the difference in electric potential energy per unit charge between two points.

7. Electrical charge - электрический заряд. Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.

8. Electric potential difference (разность пртенциалов) - is the difference in electric potential energy between two points per unit electric charge.

4. Грамматика

1) “What time does the film start, Peter?” I asked Peter what time film started.

2) “Do you watch television every evening, Chris?” The interviewer asked Сhris if watched television every evening.

3) “Why did you apply for the job?” asked the sales manager. The sales manager asked why I had apply for the job.

4) “Are you taking much money with you to France?” My bank manager wanted to know if I was taking much money with me to France.

5) “When will I know the results of the examination?” Maria asked the examiner

when she would know the results of the examination.

6) “Are you enjoying your flight?” The flight attendant asked me if I was enjoying my flight.

7) “How does the photocopier work?” I asked the salesman how the photocopier worked.

8) “Have you ever been to Japan, Paul?” Sue asked Paul if he had ever been to Japan.
