Question

Is every emf a potential difference? Is every potential difference an emf? Explain.

a) Yes, every emf is a potential difference.

b) No, not every emf is a potential difference.

c) Yes, every potential difference is an emf.

d) No, not every potential difference is an emf.

Answer 1

Emf is a special type of potential difference. Every emf is a potential difference, but not every potential difference is an emf.

Step-by-step explanation:

Emf (Electromotive Force) is not a force, but rather a special type of potential difference. Specifically, emf is the potential difference of a source when no current is flowing. On the other hand, potential difference refers to the difference in electric potential between two points. In summary, every emf is a potential difference, but not every potential difference is an emf.
