Answer

Explanation:

Step1: Draw best - fit line

Draw a straight line that passes as close as possible to all the plotted points on the graph.

Step2: Find emf (intercept on voltage axis)

The emf ($\epsilon$) is the value of the potential difference (V) when the current (I) is zero. Read the value where the best - fit line intersects the potential difference axis.

Step3: Find internal resistance (slope)

The internal resistance (r) of the battery can be calculated using the formula $r =-\frac{\Delta V}{\Delta I}$. Select two points on the best - fit line, calculate the change in potential difference ($\Delta V$) and change in current ($\Delta I$) between them, and then find the slope.

Step4: Calculate current

If the internal resistance (r) and emf ($\epsilon$) are known, and we want to find the current (I) for a given voltage drop across the internal resistance, we can use Ohm's law $I=\frac{\epsilon - V_{internal}}{r}$.

Since the graph and specific values are not fully provided for numerical calculation, we cannot give a final numerical answer. But the general steps for answering 1.3 - 1.6 are as above.

Answer:

No specific numerical answer due to insufficient data. General methods for 1.3: draw best - fit line; 1.4: read emf from intercept; 1.5: calculate internal resistance from slope; 1.6: use Ohm's law to calculate current.
