Ohm’s Law Equations

Ohm’s Law Definition

Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperatures remain constant....

Ohm’s Law Explanation

Ohm’s Law is one of the fundamental laws of electrostatics which state that, the voltage across any conductor is directly proportional to the current flowing in that conductor. We can define this condition as,...

Ohm’s Law Formula

Under the condition that all physical parameters and temperatures remain constant, Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it....

Ohm’s Law Graph

Ohm’s Law holds good when physical conditions like temperature and others are constant. This is because of the fact that the current flowing through the circuit varies by changing the temperature. Therefore, in such cases when physical factors like temperature come into play, Ohm’s law violates. For example, in the case of a Light bulb, where temperature increases when the current flowing through it rises. Here, Ohm’s Law doesn’t follow....
