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).
A dc source is connected to a series RLC circuit by a switch that closes at t=0, as shown
in Figure P4.61. The initial conditions are i(0+)=0 and vC(0+)=0. Write the differential
equation for vC(t).Solve for v C ( t ), if R = 20 Ω.
