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).
The initial energy in the circuit is zero. The ideal
voltage source is 120u(t)V.
1. a) Find I(s).
2. b) Use the initial- and final-value theorems to find i(0+) and i(∞).
3. c) Do the values obtained in (b) agree with known circuit behavior?
Explain.
4. d) Find i(t).
