Experiment 4: LCR Circuit. |
LCR circuit For the case where the source is an unchanging voltage, the second order differential equation governing the current in the LCR circuit is :
For the RLC circuit, there are two important parameters,
A useful parameter is the damping factor, ζ which is defined as the ratio of these two, The general solution of the differential equation is an exponential in either root or a linear superposition of both, where, Based on above one gets different condition of oscillatory response, via., underdamped, overdamped and critically damped.
