The resistance of a given wire is obtained by measuring the current flowing in it and the voltage difference applied across it. If the percentage errors in the measurement of the current and the voltage difference are 3% each, then the error in the value of resistance of the wire is : (in %)
The current I and voltage V graphs for a given metallic wire at two different temperatures $T_1$ and $T_2$ are shown in the figure. It is concluded that:
A potential divider circuit is shown in figure. The output voltage V0 is :

Ohm’s law
In a conductor, if all external physical conditions like temperature and pressure are kept constant the Current flowing through a conductor is directly proportional to the Potential difference across two ends.
$$
\begin{gathered}
V \propto I \\
V=I R
\end{gathered}
$$
$R$ - Electric Resistance
-
The graph between V and I
The slope gives the resistance
-
The graph between V and I at different temperatures
Here$\mathrm{T} 1>\mathrm{T} 2$.The resistance of a conductor increases with increase in temperature
