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 the circuit of Figure P5.72 initially stores
no energy. Switch S1 is open and S2 is closed. Switch
S1 is closed at t = 0, and switch S2 is opened at t = 5 s.
Determine an expression for the capacitor voltage
for t ≥ 0.
