So state ohm's law in words, so just indicate and then from there you can either write it down I'll also write it down if you haven't got anything to write it's fine you can still write it down when you replay this video because I'm going to make it available at the end of this lesson. 

So guys if you haven't subscribed please do subscribe so that you don't miss any uploads. Okay so ladies and gentlemen ohm's law in words states as follows okay, the potential difference across a conductor, right the potential difference across a conductor is directly proportional to the current in the conductor at constant temperature okay. 

Guys there's a condition to this, provided that the temperature and all other physical conditions are constant. Okay so I can just write it down, the potential don't mind my handwriting as long as you can hear what I say. The potential difference across a conductor is directly proportional to the current in the conductor at constant temperature. Okay and that condition can just write it in breakers to say provided a temperature and all other physical conditions are constant. 

So guys remember these are the wires right and you know sometimes the wires may hit so when we're dealing with circuits we assume that the temperature of these wires remains the same and there's no heat generated on those wires okay and again we assume that the ammeters and the voltmeters are not having any impact on the circuit. 

That means if that ammeter has got a certain amount of resistance we just ignore it and assume it only measures the current without having to tamper with the current flow in there or it doesn't have any resistance which resists some of the current flow.
