Question

Is ohm's law states V is directly propotional to I or I is directly propotional to V. How ? Give reason.

Answer 1

v is directly proportional

Answer 2

Ohm's lawstates that thecurrentthrough aconductorbetween two points is directlyproportionalto thevoltageacross the two points. Introducing the constant of proportionality, theresistance,one arrives at the usual mathematical equation that describes this relationship:whereIis the current through the conductor in units ofamperes,Vis the voltage measuredacrossthe conductor in units ofvolts, andRis theresistanceof the conductor in units ofohms. More specifically, Ohm's law states that theRin this relation is constant, independent of the current.
