Intended for experimental study, physics laboratory, conducting physics experiments on: Electricity and electrodynamics. The electric current as a function of voltage and electrical resistance in a conductor, Ohm's first law. The quantity electrical resistance. Factors influencing the electrical resistance of a conductor. Measuring voltages and currents. Tables and graphs. 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.
