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 , the resistor is
adjusted for critical damping. The initial capacitor voltage is 20 V, and
the initial inductor current is 30 mA.
1. Find the numerical value of R.
2. Find the numerical values of i and di/dt immediately after the
switch is closed.
3. Find vC(t) for t≥0.
