i hav a research task for motors and generators and cant find anything on it .... 1st part is "discuss the impact of the development of transformers on society , and the second part is gather analyse secondary information to discuss the need for transformers in the transfer of electrical energy from a power station to its point of use .... can somone plz give me some information on that ..plz

Primarily, transformers have impacted society in that they convert electricity so it is suitable for use in the home by domestic consumers. Transformers allow for the safe distribution of AC electricity in urban and suburban areas, as well as allowing AC to be transmitted over large distances without significant power loss.
As a result, transformers, along with generators, have provided a better quality of life for society because consumers are able to use electricity to make tasks more efficient, and for the use of luxury items.
That's all I can conjure off the top of my head. Check your textbook. It might have some useful information. Or try your library for different textbooks. You could also look at some of the Physics resources on boredofstudies.org. Try searching "bob emery" in Google as well.
As for the second part, I can't exactly just give you information about it because the information is supposed to be from secondary sources, and I presume the source needs to be referenced thoroughly in your bibliography. But I can give you a quick summary:
Basically, the transformer steps the voltage of the electricity up or down depending on the circumstances. Voltage is stepped up if the electricity needs to be transmitted over large distances from the power station to local substations to minimise power loss. There will be transformers at the power station that do this. It is then stepped down using transformers at the substation to homes so that the electricity is safe for domestic use.
Also, smaller transformers are used in small appliances like hair-dryers, otherwise it could destroy components in the appliance.

Zingerburger's response to the impact of transformers on the society does not have sufficient information to receive a full mark.
First he has covered the part the transformers play in the transmission of electricity, however he has not included the role the step up and step down transformers play at home.
The general supply voltage supplied in the Australian homes are 240V. However some household appliance may require higher or lower voltage.
Step-up transformers are used in CRT (Cathode Ray Tube) Monitors and Old TVs to step up the voltage.
Step-down transformers are used in mobile phone chargers and delicate elctrical appliances
