State and explain ohm's law

Text Solution

Verified by Experts

Ohm.s law: The law states that , at the coonstnat temperatures, the steady current flowing through a conductor is directly proporational to the potential difference between the two ends of the conductor.
`{:(i.e."," , I alpha V), ( or , I = 1/R V ), ( therefore , V = IR ), ( or , R = V /I):}`
Resistance of a conductor is defined as the rqatio of potential defference across the conductor to the current following through. it THe unit of resistance is ohm `(Omega)`
