Question

State ohm's low .give its failure

Answer 1

heyyyyy mate.....

Ohm's law states the relationship between voltage, current and resistance. According to this law, the amount of electricity passing through a conductor between two points in a circuit is directly proportional to the voltage across the two points, for a particular temperature.

Ohm's law failed because the graph between V and I is expected to be a straight line which is not obtained for higher values of current for Thyristors the relation between V and I is not unique as we obtain more than two values of I for the same V.

hope it helps.....

plzzz mark as brainliest..........
