These electrons constitute the current flow in the external circuit.

The current through an ideal voltage source is completely determined by the external circuit.

A generator forces electric current to flow through an external circuit.

Electric current is carried by electrons in the external circuit.

Interaction between the plasma and an external circuit is also available.

The current also requires an external circuit to generate, using a system known as a charge pump.

The study is grounded on the ability of biological systems to generate weak current into external closed circuit.

These electrons then flow through an external circuit where they can do work.

The separate extraction of those carriers to an external circuit.

A generator forces electrons to flow through an external electrical circuit.
