Question

We use a battery to cause a continuous potential difference by getting charges to separate. Explain why the terminals of a battery have to be connected together before current flows. _______________________________________________________________________________ ____________________________________________________________________________[2]

Answer 1

Answer:

To create an electric potential difference between the ends of the conductor.

Explanation:

For current to flow, there must exist an electric potential difference between the ends of the conductor. This PD is provided by the electromotive force stored within the battery. Unless there is a connection between the terminals no PD will exist between the terminals.
