Laboratory installation "Study of the inductance of solenoids" by Naurash
The laboratory setup consists of a tabletop metal stand on which the electrical circuit under study is assembled, an oscillographic voltage sensor, power supplies and electrical circuit elements. The elements of the electrical circuit are mounted in special boxes, on the front side of which there is an element designation. The DC power source is connected to the electrical circuit containing the solenoid through a push-button switch. Data recording is carried out using an oscilloscope voltage sensor, which records the voltage on two selected elements of the electrical circuit. The solution to the measurement problems posed in the laboratory work is provided by three computer scenarios for obtaining and processing data. To find the characteristic rise or fall time of the current in the circuit, determined by the inductance value, the experimental curves are approximated by exponential dependences. In an alternating current circuit, inductance is determined based on the slope of a straight line that approximates the dependence UL / UR = F(ω). The data for its construction is taken from the screen and entered into the table using the apparatus with vertical (time characteristics) and horizontal (sine wave amplitude) markers.
