1 3584Which of the following statements are correct for Ohm?s Law? (1) Electric current across the conductor and the multiple of the potential difference of conductor indicate resistance (2) The ratio of potential difference of conductor and electric current across the conductor is always constant (3) If all the physical states are constant, then potential difference across the conductor is directly proportional to its passing electric current (4) If all the physical states are constant, then the potential difference across any matter which conducts electricity is inversely proportional to its flowing current
