Function

Intended for experimental study, physics laboratory, carrying out physics experiments on: Electricity and electrodynamics. 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. Understanding the assembled circuit. Measuring voltages and currents. Table and graph. The V versus i graph and the meaning of the angular coefficient. 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 magnitude of electrical resistance. Factors that influence the electrical resistance of a conductor. 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. The wire bridge and the Wheatstone bridge, single reading method. The Wheatstone bridge and the wire bridge. A process that compares electrical resistances. Balancing the wire bridge, observing the reading on the ammeter. Determining the lengths A and B of the resistive wire in the bridge equilibrium condition. The expression that allows to determine the unknown resistance using the wire bridge in the equilibrium condition. Determining with the Wheatstone bridge the value of the resistance Rx. Calculation of the relative percentage error, etc. Note: Does not include measuring instruments, auxiliary wire connections and electrical power supply.
