If the bulb is fed by a current from a source of potential difference 230 V, how much current will flow through it? Example 2 : The length of a conducting wire is 50 cm and its radius is 0.5 mm. If its resistance is 30Ω, what is the resistivity of its material? Example 3 : A current of 0.24 A flows through a conductor when a potential difference of 24 V is applied between its two ends. What is its resistance? Example 4 : Determine the current that will flow when a potential difference of 33 V is applied between two ends of an appliance having a resistance of 110 Ω. If the same current is to flow through an appliance having a resistance of 500 Ω, how much potential difference should be applied across its two ends? Example 5 : Determine the resistance of a copper wire having a length of 1 km and diameter of 0.5 mm.
