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).
Assume that the circuit shown in Figure P5.73 is
underdamped and that the circuit initially has no
energy stored. It has been observed that after the
switch is closed at t = 0, the capacitor voltage reaches
an initial peak value of 70 V when t = 5π/3 μs and a
second peak value of 53.2 V when t = 5π μs, and it
eventually approaches a steady-state value of 50 V.
Explain how to modify the circuit so that the first peak
occurs at 5π μs. Assume that C = 1.6 μF.
