Physics
In an experiment of verification of Ohm's law, following observations are obtained.
| Potential difference V (in volt) | 0.5 | 1.0 | 1.5 | 2.0 | 2.5 |
|---|---|---|---|---|---|
| Current I (in amp) | 0.2 | 0.4 | 0.6 | 0.8 | 1.0 |
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.
