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 circuit at the time
the current source turns on. Given that ig=100u(t) A:
1. a) Find Io(s).
2. b) Use the initial- and final-value theorems to find io(0+) and
io(∞).
3. c) Determine if the results obtained in (b) agree with known circuit
behavior.
4. d) Find io(t).
