Conductance: According to Ohm’s law, ” the potential difference across the conductor is directly proportional to the current flowing through it”. Mathematically, V ∝ I, where ‘V’ is the potential difference in Volts and ‘I’ is the current in Amperes. V = I x R, where ‘R’ is constant of proportionality known as Resistance of the conductor. Resistance of any conductor is the obstruction to the flow of current and is directly proportional to the length (l) of the conductor and inversely proportional to its area of cross-section (a) i.e. R ∝ l/a or R = ρ x l/a, where … Continue reading What is Conductance?
