Description

The aim of the experiment P1.5.3.1 is to investigate free harmonic rotational oscillations of the type

To distinguish between oscillation and creepage, the damping constant Δ is varied to find the current I0 which corresponds to the aperiodic limiting case. In the oscillation case, the angular frequency ω is determined for various damping levels from the oscillation period T and the damping constant Δ by means of the ratio

of two sequential oscillation amplitudes. Using the relationship

we can determine the characteristic frequency ω0.
