the emf .of a cell is E .If the amount and size of all its components are doubled then the emf will be (A)2E(B)E/2(C)E(D)E2​

Answer 1

Answer:

E

Explanation:

The EMF of a cell  depends upon the chemcial reactions among the chemicals used. It is independent of other factors like the size of the cell or the length of the electrodes. Therefore, if the size of all the components are doubled, the EMF will remain unchanged i.e. it will still be E.

Answer 2
