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).
In the circuit below, the switch is closed at t=0 s. It is known that the voltage across the capacitor at t=0.2 s is Vc( t = 0.2 ) = 10.31 V. What is the initial energy of the capacitor in this case? Calculate.
