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 circuit is scaled so that the 100 Ω resistor is replaced by 500 Ω resistor and the 160 μH inductor is replaced by a 2
mH inductor.
1. What is the scaled value of the capacitor?
2. Find the frequency for which the impedance Zab is purely resistive
for the scaled circuit.
3. How is the frequency you found in part (b) related to the frequency
for which the impedance Zab is purely resistive in the un-scaled
circuit?
