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).

opened.
a) Derive the differential equation that governs the behavior of i2 if L1 = 4 H, L2 =
16 H, M = 2 H, and R0 = 32 Ω.
b) Show that when ig = 8 - 8e-t A, t ≥ 0, the differential equation derived in (a) is
satisfied when i2 = e-t – e
-2t A, t ≥ 0.
c) Find the expression for the voltage v1 across the current source.
d) What is the initial value of v1 .Does this make sense in terms of known circuit
behavior?
