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]

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.

Before the current flows, the battery terminals should be connected together in order to complete the circuit so there is continuous flow of charge.

Continuous flow of charge in a battery

There is a continuous potential difference in a battery which causes the charged particles to flow.

There are two terminals in the battery - positive terminal and negative terminal. These terminals should be connected so as to complete the circuit and so that there is continuous flow of electrons in the circuit.

In this way the current flows through the circuit.
