Question

verify the ohms law step to step....plz.... ​

Answer 1

Ohm’s law states that at a constant temperature, current I through a conductor between two points is directly proportional to the potential difference or voltage, V, across the two points.  Thus, the ratio V: I is constant, and is called the resistance, R, of the conductor.  In other words, V/I = constant = R, or V = IR, where R is a constant for the given metallic wire at a given temperature and is called its resistance.  The S.I unit of Resistance is ohm. If the values of V are plotted against I on a graph paper, the graph is known as a V-I graph. As the temperature of a conductor rises, its resistance also increases.
