Answer:
According to Ohm's law, the potential difference (V) across the ends of a resistor is directly proportional to the current (I) through it provided its temperature remains the same. ... The slope of this straight line graph gives the resistance R of the resistor.

Answer:
Ohm's law states that the amount of electric current through a conductor in a circuit is directly proportional to the voltage across it. Ohm expressed his discovery in the form of a simple equation, describing how voltage, current, and resistance relate to each other: V=IR. He published his work in 1827.
