1. The study of electricity began with Dr. Gilbert 2. He lived at about the same time as Galileo 3. In 1600 he wrote a book describing experiments on electricity and magnetism 4. Russia played an important part in the development of electrical science 5. In spite of difficult conditions under which the scientists and inventors had to work in tzarist Russia they discovered electrical phenomena of great importance 6. In addiotion to that Russian scientists and inventors always tried to find practical application for the phenomena discovered 7. The first work on electricity published in Russia was that written by the father of Russian science Lomonosov 8. Lomonosov was the first to find that heat, lignt and electricity are different forms of movement 9. He was also the first to find the electrical nature of some atmospheric phenomena. 10. Academician Petroff was the first scientist in the world who observed the phenomena know later as the electric arc.

1. Current is a flow of electricity through a circuit 2. There are two types: a direct and alternating. 3. A direct current flows through a conducting circuit in one direction only. 4. An alternating current is a current that changes its direction of flow through a circuit. 5. Alternating current flows in cycles. 6. The number of cycles per seconds is called frequency of the current. 7. It is easy to transform a.c power from one voltage to another by transformer. 8. Transformers are also used to step down the voltage at the receiving point. 9. A.c can be changed into d.c. 10. But it is seldom necessary.

Завдання №2 Answer the questions
