What is ohms' law? How will you verify this law in the laboratory?
Answers
Ohm's Law. Ohm's Law states that the potential difference between two points is directly proportional to the electric current. ... Resistance is the property of conductor which resists the flow of electric current through it. SI Unit of resistance is ohm.
Verification is lengthi so I can explain
PLEASE MARK AS BRAINLIEST
Objective:
To verify the Ohm's law.
Statement of Ohm's Law:
Ohm’s law states that at a constant temperature, current 'I' through a conductor between two points is directly proportional to the potential difference or voltage 'V', across the two points. That is,
V propto I
or frac{V}{I} = constant = R
or V = IR
Thus, the ratio V : I is a constant. This constant is called as the resistance (R) of the conductor.
