                                                  Chapter # 13                                               

                                         How to use electricity?

If an individual or a person buys any type of electronic item, for example, a clock, tape recorder or a mobile from market, the seller tells few safety precautions which he thinks are correct according to his knowledge to the buyer about the sold item. In buying the clock, the buyer is told to follow flowing main points for long life of the clock.
  • keep away the clock from water
  • Put off clock during heavy manual work, for example during cutting of wood or stones etc.
  • Keep away from reach of children.
  • Use cell of good quality.
  • Clock will not easily be damaged if it is used by a single person.
In case of purchasing of a mobile, the buyer is instructed to act upon flowing main points for his own interest.
  • Mobile should not be charged unless & until “Battery low” signal appears on the screen.
  •  Battery charge could be over/ finished by using camera or listening of F.M radio & audio or watching of videos.
  • Mobile should be turned OFF while charging.
  • Save mobile from sun and water.
  • Keep away mobile from thieves
  • Use cover or casing to avoid any damage to mobile etc.
  • At last, the buyer is being told that adopting above mentioned precautions, mobile would work for a long time.
Similarly, if a buyer wants to buy tape recorder and he also wants to buy any cheap but of a good quality tape recorder of a reputable company. The seller or shopkeeper shows adapted tape recorder and in addition, he elaborates following guidelines to buyer:
  • In case of use of cells, the batteries or cells should be changed in time, otherwise any leakage from cells may damage electrical or electronic circuit.
  • If the tape recorder is operated by electricity, good quality adopter should be used and voltage level should be maintained as per requirement of the system.
  • Tape recorder buttons repeatedly not be touched.
  • Tape recorder should be kept away from reach of children.
  • Antenna of tape recorder should not be used frequently while listening radio or the antenna should not be pulled out at its full length because by using antenna at its full length, radio will catch many channels at the same time.
Now, obviously, a person can listen to a channel at a time. To listen to a specific channel without any interference, he tunes the radio. The filter circuit inside the radio will undermine by filtering the required channel among many channels catch by using of antenna at its full length.
This will affect the performance of radio and it will be disfigured very soon. It may also happens that sometimes, using of antenna for a long period, if a person tries to listen radio without antenna, the radio will not catch any channel because it becomes habitual of using of antenna. If a cash amount was spent on buying the tape recorder, good quality cassette may also be bought for the tape recorder.
The cassettes available in local market at the rate of Rs. 30/- or 40/- rupees may destroy the tape recorder badly.
  • Cassette cover might break by frequent changing of cassette or mechanical malfunction may arise in the system.
The aim of mentioning of all these points here is only to highlight that a person who earns money by physical hardworking and buys something or invest to construct any scheme, he or she should be worried about his investment or project or scheme or plan and the project or scheme or programme or plan should be beneficial to him or her.
Since nothing is available freely in market or bazaar and ultimately one has to spend money for everything. Every one of us must think before starting any work or project or scheme whether it is beneficial or not to the society or the individual.
