# The graph shows the terminal voltage \(V_T\) as a function of current \(I\) for a non-ideal battery. An external load resistor of resistance \(R = 9.0\text{ }\Omega\) is connected across the terminals of this battery. What is the terminal voltage across the battery when connected to this load resistor?

The graph shows the terminal voltage \(V_T\) as a function of current \(I\) for a non-ideal battery. An external load resistor of resistance \(R = 9.0\text{ }\Omega\) is connected across the terminals of this battery. What is the terminal voltage across the battery when connected to this load resistor?

![A two-dimensional Cartesian graph plotting terminal voltage \(V_T\) on the vertical axis against current \(I\) on the horizontal axis. The vertical axis is labeled 'Terminal Voltage \(V_T\text{ (V)}\)' with major tick marks labeled 0, 3, 6, 9, 12. The horizontal axis is labeled 'Current \(I\text{ (A)}\)' with major tick marks labeled 0, 1, 2, 3, 4. A single straight solid line with a constant negative slope starts at the vertical axis intercept at \((0, 12)\) and goes linearly down to the horizontal axis intercept at \((4, 0)\). Thin dashed grid lines mark the coordinate intersections at integral values. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-graph-1-1785830997-qTHVtn.jpg)
