Il circuito Resistenza Induttanza è banale. Sei proprio sicuro?

The RL circuit is often considered one of the simplest examples of electrical engineering and circuit physics. But is it really that simple? In this video experiment, we fully analyze the behavior of an inductor inserted in a series RL circuit, starting from Kirchhoff's law and ending with the formulation of the differential equation describing the system. We'll see why the current follows an exponential trend and the physical meaning of the time constant τ = L/R. In addition to the theoretical part, we'll perform some laboratory measurements to compare the mathematical model with real experimental data, verifying the validity of the analytical solution. The video includes: 1. Mathematical derivation of the RL circuit 2. Solution of the differential equation 3. Meaning of the time constant 4. Analysis of the current curve 5. Comparison between theory and experimental measurements 6. Physical interpretation of the transient
