the value of the voltage gradient when 5 volts electromotive force is
applied at its ends?​

Answer 1

i hope it's helpful for u..

Answer 2

Answer:

the value of the voltage gradient of the potentiometer is 1 V/m.

Explanation:

Given the length of the wire of the potentiometer $L= 5 ~m$

Applied electromotive force, $V=5~ V$

Voltage gradient(K) is the difference in electrical potential per unit length, which can be written as $K=\frac{V}{L}$

where V is the potential difference between two points and L is the distance between two points.

Thus, the voltage gradient of the potentiometer is

$K=\frac{5}{5}=1~V/m$

Therefore the value of the voltage gradient is 1 V/m.
