The terminal potential difference \(V\) of a battery is measured for different currents \(I\) drawn from it by adjusting an external rheostat. The graph of \(V\) against \(I\) is shown.

0 0.4 0.8 1.2 1.6 2.0 2.4 0 2 4 6 8 10 12 14 I / A V / V


The battery is then connected to a single \(4.0\ \Omega\) resistor. What power is delivered to this external resistor?
