My thought on this is that, if you just plugged both cords, then current will begin to travel from the cables to the phones, my thought actually (though i have not verified it through science yet)is that the current will travel and get to the phone faster in the shorter cord initially but when there is also a contact in the longer cord , the current will saturate the longer cord as well and there is no difference again , because there is a direct contact now, just like a ladder touching the roof and the ground. What i am sure of 'though is the quality of the cable, charger pass charger mehn! |

Lol. No it doesn't. Speed of electricity is too high that it renders the lenght almost negligble. Howbeit, the lenght can come into play if the material of the charger is of low quality so there will be higher resistance thereby leading to lower current getting to the phone. |

Hello... obidient in the house . Una own person for BBN is up this week for eviction. Try to vote for him. Start ur obidient from there. Don't allow APC and pdp to finally label obidient social media party. Campaign for him. Obidient children can do it. Vote for eloswan.... |

Na common sense now The road wey the light go waka inside long cable far small But short cable the light go sharp sharp enter the phone You see the physics now *Lights blunt* |

MaDaRa01: That should be due to the quality of wire cable used |

Scottz:I was about to reply this , I just dey read niqqas tryna be albert Einstein , my phone cord sef long but e dey charge fast pass my old short charger � I don’t know what this niqqas be talking about longer the cord the greater the resistance |
Re: Does The Length Of Charging Cable Affect Charging Speed by BJanta: 4:26pm On Sep 06, 2022 |
MaDaRa01: Including the cross-sectional area of the wire and the conductivity of the material or metal the wire is made of. Conductivity of metals in increasing order is from Silver to Copper to aluminium in that order. Which means that Copper is a better conductor than aluminium and that is why it used moztly as wires and cables.Silver that conducts better is too expensive.But you find out is that most electrical wires and cable nowadays are made of coated alumunium wires . And these are essentially the fake ones. |

Shorter cable are faster than the long cable If you observe well if you have a power bank use the shorter cable for the power bank it will not use up to 4 hours my 20,000ah power banks is full Cable matters a lot |

So what is the rational or design behind the rating on a charger written output 5v 2A . I thought this output rating should mater too when buying chargers not just the length. |

yinkabeauty:lol, they can't be constant for you to have a proper charger |
Re: Does The Length Of Charging Cable Affect Charging Speed by Alusiizizi(m): 4:37pm On Sep 06, 2022 |
MaDaRa01: YES. Resistivity x Length = total resistance. Voltage/total_resistance=current. current=(directly proportional to charging rate). Of course there are disclaimers to add. Most chargers will include current limiting mechanisms to protect the charger(as well as the charged device). This is particularly true(actually essential) with mosfet based chargers, which is how those cheap China chargers are built(no wonder they are so light weight). For "original" transformer based chargers, current limitation is not nearly as big a problem and a simple fuse addresses that issue. |

Re: Does The Length Of Charging Cable Affect Charging Speed by Kayharry(m): 4:39pm On Sep 06, 2022 |
slawomir: Your type of charger determine if it's going to do fast charging or not. The wire doesn't determine that |
Re: Does The Length Of Charging Cable Affect Charging Speed by yinkabeauty: 4:40pm On Sep 06, 2022 |
MrReeseG: Initially, the current will travel a longer distance but when it gets to the target with constant supply , the current becomes saturated and fill the cord, then speed is insignificant, thats why a long wire shocks you at a very fast speed when touched, sometimes ‘’common sense‘’ may not be enough to explain science. |

Re: Does The Length Of Charging Cable Affect Charging Speed by yinkabeauty: 4:51pm On Sep 06, 2022 |
phemmyfour: oga, your explanation was no!, lenght does not affect speed of current , that it's amp and input volt and what determines these, the source of power and the charger itself, so the question is if you have the same chager head, the same source of power, the same quality of cord but one cord is longer than the other ,would their not be effect? that's the question. |
Re: Does The Length Of Charging Cable Affect Charging Speed by Rajiolaade: 4:54pm On Sep 06, 2022 |
MaDaRa01:p=vi power= voltage × current , in bulk electricity transmission, current is converted to very high voltage by transformer action I.e step up xformer thereby allowing for very high power to travel long distance with minimal current loss i²r loss with small cross sectional area cable ,the only advantage a.c voltage has over d.c voltage that makes a.c suitable for worldwide utilization.From power stations transformers step voltages up for transmission then step down for utilization at sub stations.

Re: Does The Length Of Charging Cable Affect Charging Speed by yinkabeauty: 4:55pm On Sep 06, 2022 |
Kayharry: the type of charger, the source of power, the quality of wire too, and to an unsignificant extent the length too. slawomir |

Jazzman01: This is bull, determinant parameters are: inductance, capacitance, resistivity, conductance of the material used as a conductor. (Simply meaning say na the kain wire china ppl use couple ur cord dey determine whether na original abi na fake) |

smoke555: and resistivity has no connection with length? |
Re: Does The Length Of Charging Cable Affect Charging Speed by Livadesh: 5:04pm On Sep 06, 2022 |
MaDaRa01: V= IR Voltage = current x resistance Resistance (R) = ρ L A Resistance is a function of length and area. The more the length, the more the resistance. The more the resistance to flow of current, the slower the gadget is charged. Do you understand now? |
