Choose the appropriate English equivalents

1. ближе— 1. close; 2. closer; 3.the closest

2. лучше— 1. good; 2. better; 3. the best

3. больше— 1. the most; 2. more; 3. Much

4. самый маленький— 1.small; 2. smaller; 3. the smallest

5. самый большой— 1. the largest; 2. large; 3. larger

6. выше—1. high; 2. higher; 3. the highest

Remember the spelling: big – bigger

1. The farther the grid is from the cathode, the more the plate current is. 2. The wider the distance between the grid wires, the more the plate current is. 3. The higher the temperature, the lower the conductivity of a me­tallic conductor. 4. The lower the temperature, the better the conductivity of a metallic conductor.

5. The slower the electrons move, the easier it is to stop them and return them to the space charge. 6. The closer the grid is to the cathode, the more control it will have on elec­tron flow to the plate. 7. The more heavily the material is doped, the lower its electrical resistance will be. 8. The hotter the cathode becomes, the more electrons it emits per unit time (в единицу времени). 9. As the electrons move out into space, they form a cloud (облако) of negative charges. The larger this cloud becomes, the more opposition it offers to additional electrons leaving the cathode. 10. The more nega­tive the grid, the less the plate current will be. 9. The greater the load resistance of a tube amplifier, the greater is the voltage amplification.
