inductive reactance of 8 ohms is connected in parallel with a capacitive reactance of 18 ohms; this combination is then connected in series with a variable resistance. For wht value of resistnace will the power factor be 0.5, and what current and power will the circuit take if the impressed emf is 118 volts.
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).
