Aim To determine resistivity of two wires by plotting a graph for potential difference versus current. Apparatus and Material Required Principle According to Ohm’s Law, the current passing through a conductor is directly proportional to the voltage applied across it, as long as the conductor’s temperature and other physical properties remain constant. If I be the…
