Give statement of Ohm's law. Get an expression for it Draw a circuit to establish Ohm's law in laboratory What is the limitation of Ohm's law. Draw a graph between current and potential difference for Ohm's law.
Answers
Answer:
the potential difference v , across the end of a given conductor is directly proportional to the current flowing through it. provided temperature and other factors remains same
Answer:
OHM's LAW
George Simon Ohm found the relationship between the current (I) flowing through a conductorand potential difference (V) across the terminals of a conductor using the circuit diagram. He observed that the potential difference and current varied linearly.
Ohm’s Law He stated that the electric current flowing through a conductor is directly proportional to the potential difference across its ends, under standard temperature and pressur conditions.
Where “R” is the proportionality constant for the given metal at given temperature and is called resistance.The graph between V and I is always straight line with slope equal to R.
