ABSTRACT
Researchable lamp is a source of light that is generated from a D.C sources of supply this D.C sources is a battery that can also way be charged when it current and voltage ruse
I decided to work on this as my project because its importance. It is very portable and help the a lot during night reading
It also serves as an immanency sources of light mostly when there is failure from out public power supply (P.H.C.N)
INTRODUCTION
Electricity and electronic has done a lot of good to our society. Sometimes I imagine how the entire world would have look like without light or electricity. Electricity has a lot of advantages both in our homes and industrial uses. Some of then include cooking washing of cloths (laundry) milling and as sources of light e.g rechargeable lamps
Rechargeable lamp is one improatnt devoice that comprises the use of electricity and electronics. Due to it great importance to the society at large decided to use it as my project topic.
When I say electricity and electronic someone may be imaging if there is any difference among the two. But the answer is yes. This is because electricity does not involves component like diodes capacitors transistor etc but electronic is the embody of this discrete component to from a working circuit.
Note that electricity is just the stepping down of voltage by using a transformer to pass current and voltage to the circuit only.
Nevertheless my concentration is on rechargeable which serves as a sources of light in our homes in the absence of electricity from our public power supply
