Physics
Home Work
My physics teacher gave my team a home
work. The home work was made a circuit of electric. We made it when we were holiday
on Monday morning at Agung’s house. First i merged
the batteries by cellophane tape strongly. After that i connected the batteries
to the three of LED lamp but just one lamp lighted. I was so tired.
I didnot
know what was
the mistake. I and Arung
added one battery again because i thought the lamp needed more voltage. After
we added one battery we tried to connected the batteries to the lamp, quickly the
lamp burned. After that I didn’t know what should be we did. The time is two p.m we were so tired and we end made the home work.
I brought the electric circuit to my home. At home I tried again repaired the electric circuit, I removed one battery and changed the circuit from parallel to series. But that didnot gave me a solution, the lamp was still just one
lighted. After that I changed the three of
LED lamp to the three of filament lamp, and the result three of filament lamp
was lighted and I was so happy. After
that I asked to my friend, why the LED lamp cannot light together? He told me which LED lamp couldnot light because the LED reverse in set and LED
lamp couldnot set in series circuit because if one dead others also dead. After I know that, I set the LED lamps to parallel circuit and not reverse in set. After I connected the LEDs to the batteries and all LED
lighted together. Oh, thanks God!Originally posted::Zomplax87
