Question

define voltage drop in the cell

Answer 1

Voltage drop is defined as the amount of voltage loss that occurs through all or part of a circuit due to impedance. A common analogy used to explain voltage, current and voltage drop is a garden hose. Voltage is analogous to the water pressure supplied to the hose.

Answer 2

Definition

The work done in carrying a unit positive test charge through the electrolyte in the electrolytic cell is called voltage drop.

$\mathsf{Voltage\:drop\:\:v=\frac{w}{q}}$

The voltage drop cannot be used by us and hence it is called the voltage drop .

The voltage drop can be written as:

V = I r

where r is the internal resistance.

Hope it helps ;-)
