Drawing characteristic curve of an ohmic conductor



Description : Video to discover the influence of resistance on a circuit, draw the current-voltage characteristic curve of an ohmic conductor and give the equation which will be the relation:
V = RI, known as Ohm's Law.

Ohmic conductor: any two-terminal device, or more generally any conductor, of which the voltage/current characteristic is a straight line passing through the origin.
Characteristic curve: A current–voltage characteristic or I–V curve is a relationship, represented as a chart or graph, between the electric current through a device and the corresponding voltage (potential difference) across it.
