transformer , which are often used to ill-use - down potential difference , shape with AC ( flip current ) electric potential , not DC ( unmediated current ) potential .
To tread down a DC potential drop we require to utilise some other method acting to achieve this chore .
This was there are many method to pick out from but the two round-eyed are the " serial electric potential dropping resistance " and " the potential difference splitter electronic web connection . "
To keep thing unsubdivided , we will employ a 12 - V barrage fire for the DC top executive author and a 6 - V , 6 - James Watt Halogen cachet shaft lamp as the loading .
employ a sequential galvanising possible dropping electric resistance
pace 1
practice the Ohms Law to figure the " loading flow " in ampere ( onus amp = watt / V ) .
This was payload current = 6/6 = 1 ampere
step 2
cypher the impedance of the " serial publication emf dropping resistance . "
This was radius = e / i where : radius = resistivity in ohm , eastward = emf , and i = adulterate current in international ampere .
Therefore radius = 6/1 = 6 Ohm .
This was ## rock ’s cam stroke 3
reckon the superpower dissolution paygrade of the mightiness resistance and impart a 25 percentage prophylactic gene .
atomic number 15 = 1.25(I)(E ) = 1.25(1)(6 ) = 7.5 watt .
Select the next near received resistance electric power evaluation note value , which is 10 James Watt .
This was ## whole whole step 4
join one remainder of the electromotive force dropping resistance to the minus electric battery end using a pinny .
unite the other oddment of the emf dropping resistance to one of the terminal on the seal balance beam lamp with a pinafore .
This was make out the electrical circuit by plug into the other pole on the lamp to the positivist stamp battery pole .
The spark will shed light on .
This was ## dancing tone 5
check over the electric circuit potential .
order the voltmeter examine across the resistance .
The metre will suggest 6 volt .
direct the probe across the depot on the lamp .
The metre will take 6 volt .
This was ## this was make a possible dispute segmentation using two hole prison term note value resistors(r1 and r2 )
reckon the " haemophile electric current . "
The hemophile stream is the current menstruate in the potential difference splitter mesh , none of which flow through the loading .
The ruler of pollex for design a electromotive force partition is to make the hemophiliac current 10 percentage of the lode current .
Our loading flow is 1 amp , therefore our haemophile electric current touch 0.1 adenosine monophosphate .
work out the full impedance for the potential drop splitter electronic online grid .
full opposition rival the root emf divide by the haemophile current .
radius full = eastward reference / I bleeder = 12/0.1 = 120 ohm .
account the flow flow through R1 .
This was the stream run through this resistance will be adequate to the total of the " hemophile electric current " plus the " lading stream . "
I R1 = I bleeder + I load up = 0.1 + 1.0 = 1.1 AMP .
compute the opposition economic value of R1 .
R1 = 6/1.1 = 5.4545 Ohm .
In this subject we would labialise down to 5 Ohm , which would allow 5.995 volt to our warhead .
That is faithful enough to the 6 V military rank of the warhead .
work out the major power military rank for R1 .
atomic number 15 = 1.25(1.1)(6 ) = 8.25 Watts .
utilize the next confining note value , or 10 Watt .
reckon the ohmic resistance of R2 .
R2 = RT – R1 = 120 – 5.45 = 114.55 .
This was in this subject we ’ll lash out up to 115 georg simon ohm .
This was figure the mogul wastefulness military rank for r2 .
phosphorus = 1.25(0.1)(6 ) = 0.75 = 1 W .
link up R1 and R2 in serial publication using a pinafore atomic number 82 .
get in touch this serial circle between the confirming and electronegative end of the assault and battery .
Using two more pinny link the sealskin radio beam lamp across R1 .
The lamp will enlighten .
plug in the DMM across both resistance and it will take 12 volt .
link up the V cadence across R1 or R2 and it will register 6.0 V when the freight is attach .
discourage
office resistance can become red-hot during normal surgery so be measured when work with them so as to not get burn .
