Question

the emf of a simple volatic cell is about

Answer 1

1.5ev is emf of voltaic cell

Answer 2

Hi,
In a simple voltaic cell the two metal plates, known as electrodes, are dipped in a solution, known as electrolyte.
For example: In the given voltaic cell, a zinc plate and a copper plate are immersed in a very dilute solution of sulphuric acid, taken in a glass vessel. The copper plate and the zinc plate are externally connected to a bulb.
The movement of electrons takes place from zinc to copper resulting in the generation of electric current.

The dry cell has a potential of nearly 1.5 V.


Cheers!
