1.	In an experiment of verification of Ohm's law, following observations are obtained. Potential difference V (in Volt)0.51.01.52.02.5Current I (in ampere)0.20.40.60.81.0 Draw a V- I graph and use this graph to find : (a) the potential difference V when the current I is 0.5 A, (b) the current I when the potential difference V is 0.75 V, (c) the resistance in circuit.
Answer» In an experiment of verification of Ohm's law, following observations are obtained. $\begin{matrix} Potential difference V (in Volt) & 0.5 & 1.0 & 1.5 & 2.0 & 2.5 Current I (in ampere) & 0.2 & 0.4 & 0.6 & 0.8 & 1.0 \end{matrix}$ Draw a V- I graph and use this graph to find : (a) the potential difference V when the current I is 0.5 A, (b) the current I when the potential difference V is 0.75 V, (c) the resistance in circuit.
