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).
11. 7.11 The switch in the circuit seen has been in position 1
for a long time. At t=0, the switch moves instantaneously to position 2.
Find the value of R so that 20% of the initial energy stored in the 30 mH
inductor is dissipated in R in 15 μs.
