Answer 1

Answer:

x=Vab/Lp

x=2/8

1/4= .25 volt

Answer 2

Given info : The length of the wire of the potentiometer is 8 meters. 2 volts potential difference is applied at its end.

To find : what will the value of the voltage gradient ?

solution : voltage gradient of potentiometer = change in potential per unit length of potentiometer

here potential difference, ∆v = 2 volts

length of potentiometer, l = 8 metre

so, potential gradient = 2/8 = 0.25 volt/m

Therefore the potential gradient of the wire of potentiometer is 0.25 v/m.
