Suppose we have a 10v battery.one end of the battery is at 10V electric potential and other is at 0V Hence,the potential difference is 10V.if we measure the voltage( p.d.) across positive terminal at 10V and the middle of the wire connecting both ends of battery will it be less??I mean,at the middle of the wire the electric will not be zero,right??(correct me if am wrong)Thanks!!
If the wire had some reasonable resistance which prevented melting of the wire and explosion of the battery; the middle of the wire would show half the potential difference between the terminals. The wire connecting the terminals becomes a potentiometer with Voltage falling linearly between the terminals (assuming uniform resistance along the length of the wire). In practice, Voltage drop on a wire supplying power to a load is proportional to the resistance of the wire divided by the resistance of the load. When the wire is the load, all Voltage drop occurs along the wire.
