Sinusoids And Phasors
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).
There is no energy stored in the inductors L1 and L2 at the time the
switch is opened in the circuit . 1. a) Derive the expressions for the currents i1(t) and i2(t) for t≥0.
2. b) Use the expressions derived in (a) to find i1(∞) and i2(∞)
