2a. The problem having discussed is of no great importance for practice.

3a.The generators constructed at the plant have no commutators.

4a.While passing through the con-ductor, resistance results in the production of heat.

5a.Insulated with polythene, the line was tested under unfavourable con-ditions.

6a.Tested under different condi-tions,the motors were put to use.

7a.When being rubbed, some sub-stances produce electric current.

8a.Being decelerated trains and be-ing descended elevators use nega-tive, or braking, torque.

9a.In what way is the transmitter being controlled in an amplitude-modulated system?

1b.The energy lost in the capacitor appears in the form of heat being generated in the dielectric.

  5. Switch board is an assemblage of controlling and indicating devices mounted upon a frame.

  6. The data obtained formed the basis for further activity.

  7. Gas coolants used to remove heat losses help to increase the current-carrying capacity of the motor’s main parts.

  8. Water power is being used to drive a dynamo.

  9. Nuclear fuel is undergoing nuclear fission.

XII. Find the participles (passage 3) in text 3 a. Define the functions of the participles.
