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).
The two switches in the circuit have been closed for a
long time. At t=0, switch 1 is opened. Then, 35 ms later, switch 2 is opened. 3. What percentage of the initial energy stored in the 150 mH inductor is
dissipated in the 18 Ω resistor?
