The graph provided shows the relationship between current \(I\) in amperes (A) and voltage \(U\) in volts (V) for a conductor. Using this information, we can determine the resistance of the conductor by applying **Ohm's Law**:

\[
R = \frac{U}{I}
\]

From the graph, at \(U = 6 \, V\), \(I = 30 \, A\).

Now, applying Ohm's law:

\[
R = \frac{6 \, V}{30 \, A} = 0.2 \, \Omega
\]

Thus, the resistance of the conductor is \(0.2 \, \Omega\).

Would you like further details or explanations on this problem? Here are some related questions to expand your understanding:

1. How does Ohm's law relate to this graph?
2. How would the graph look if the resistance was higher?
3. What would happen to the current if the voltage is doubled?
4. Can resistance change with temperature, and if so, how?
5. How can we measure the resistance of a conductor practically?

**Tip**: Always use Ohm's law to determine the relationship between voltage, current, and resistance in a linear circuit.
