Electric current as a function of voltage and electrical resistance in a conductor, Ohm's first law. The magnitude of electrical resistance. Factors that influence the electrical resistance of a conductor. Measuring voltages and currents. Table and graph. The electrical resistance offered by a conductor. Ohm's first law and the electrical resistance offered by an ohmic conductor. The relationship between the three main electrical quantities, current, voltage and electrical resistance. Electrical resistance as a function of the length and area of the conductor, Ohm's second law. The dependence of the electrical resistance of a homogeneous conductor on its length. The dependence of the electrical resistance of a homogeneous conductor on the area of its cross-section. The resistivity of the material from which the conductor is made, etc. Note: Does not include measuring instruments, wire connections and electrical power supply.
