Question

The potential. difference between two terminals can be measured by a- ammeter b- An ohm meter. c-volt meter. d-A Rheostat​

Answer 1

Answer:

Voltometre

In the case of a two-terminal device (such as an electrochemical cell) which is modeled as a Thévenin's equivalent circuit, the equivalent emf can be measured as the open-circuit potential difference, or voltage, between the two terminals.
