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).
13. 7.33 The switch in the circuit has been in position a for a
long time and v2=0 V. At t=0, the switch is thrown to position b.
Calculate 1. a) i, v1, and v2 for t≥0+,
2. b) the energy stored in the 1 μF capacitor at t=0, and
3. c) the energy trapped in the circuit and the total energy dissipated
in the 25 kΩ resistor if the switch remains in position b indefinitely
