In the circuit shown below, there was no current in the inductor before t=0. The switch was close at time t=0, and later reopened at t=1.2 s. Find the following parameters: a) Find the expressions of iL(t) and vL(t) in 0< t <1.2s; b) Determine Vr1 (t) and Vr2(t) right before the reopen of the switch at t =1.2 s. c) Determine the Vr2(t) right after the reopen the switch at t =1.2 s.

Sinusoids are defined as the mathematical waveforms that are used to describe the nature of periodic oscillations.
Circuit Theory
Electric circuits are a network that comprises of a closed-loop, which helps in providing a return path for the current through a switch. When the switch is activated, the load operates, and the current accepts a path to finish the circuit at a low potential level from the opposing high potential level. Electric circuits theory is a linear analysis that helps in establishing a linear relation of voltage and current for R (resistance), L (inductance), and C (capacitance).
