What is the ohms law?

Answer Posted / er.suresh padmanabhan.t,dharma

electric current through any conductor is directly
proportional to voltage(potential difference)applied
between the ends of the conductor at constant temperature.
current I is directly proportional to V(here V=v1-v2 if v1
is greater than v2,here v1&v2 are voltages at the ends of
the conductor)
I=V/R
i.e, V=IR
