why emf is measured in open circuit

Answers

Answered by akshaykumarks2005

Answer:

The electric charge that has been separated creates an electric potential difference that can be measured with a voltmeter between the terminals of the device. The magnitude of the emf for the battery (or other source) is the value of this 'open circuit' voltage.

Explanation:

What is EMF in a circuit?

Why is it useful to know the EMF of a circuit? Electromotive force (EMF) is equal to the terminal potential difference when no current flows. ... EMF (ϵ) is the amount of energy (E) provided by the battery to each coulomb of charge (Q) passing through
