• Users purchase electricity from the grid can not avoid the costly exercise of having to generate their own. 

• The power grid is an electrical network that connects a variety of electric generators to the suppliers of electric power. 

• To drive highly efficient electric motors such as induction motors you need three-phase power. 

• The losses, appearing in the form of heat, are equal to the current squared times the electrical resistance through which the current flows. 

•The age of electricity began in 1919. 

• Transforming is important because higher voltages suffer less power loss during transmission. 

• Modern power engineering consists of two main subsystems. 

• There are several different transformation processes, among which are chemical, photo-voltaic, and electromechanical. 

• The turbine-generator conversion process is the most economical and most common in the industry today. 

• The AC synchronous machine is the least common technology for generating electrical energy. 

• The operating costs of generating electrical energy is determined by the fuel cost and the efficiency of the power station. 

• When an extended conductor has similar potentials at its ends, the free electrons of the conductor itself are caused to drift from one end to the other. 

 • The circuit is broken when an electric device is switched off. 

• The circuit is “closed” when an electric device is switched on.  when an electric device is switched off. 

• When electrical devices are connected so that the current flows from one device to another, they are said «to be connected in series». 

• The “parallel” circuit provides two or more paths for the passage of current. 

• The “short” circuit is produced when the current can return to the source of supply under control.

• I ....... (go) home as soon as I carry out my work. 

• If he ....... (to arrive) on time we'll have dinner before we go out. 

• Mary won't go to Australia unless I ....... (to pay) for her tickets. 

• Unless it ....... (to rain) we'll go for a walk. 

• Please call me if you ....... (to need) any help. 

• A three-phase circuit, under balanced conditions has no constant, nonpulsating, instantaneous power. 

• Almost all bulk electric power generation and consumption take place in three-phase systems. 

• Most of three-phase systems are four-wire, wye-connected systems. 

• The cost of a neutral conductor is substantially more than that of a phase conductor. 

• Faulty wiring can subject an individual to ……

• When cattle drink from electric feeding troughs or are attached to electric milking machines, small …... pass through the cattle. 

• Some juries have awarded …. to farmers whose cattle have been damaged. 

• Electromagnetic …... are created whenever current moves through power lines. 

• He would open the door if he ....... (have) the key. 

• If she got good grades, she ........ (go) university.
