| ELECTRIC CURRENT 1. When the electrons flow in one direction only the current is known to be d. c. that is. direct current. 2. The simplest source of power for the direct current is a battery, (i. . from the negatively charged terminal to the positively charged terminal). 3.The letters a. c. stand for alternating current 4. The current under consideration flows first in one direction and then in the opposite one. 5. The a. c. used for power and lightning purposes is assumed to go through 50 cycles in one second. 6. Yablockov was the first to apply a. c. in practice. 7. The first source of continuous current was constructed by Volta in 1800. 8. Now we cannot imagine modern civilization without the electric current. 9. Every student is familiar with the important part which the electric current plays in everyday life. 10. We used many electrical devices in our everyday life: electrical lamps, vacuum cleaners, refrigerators, washing machines, and so on. 11.
