A coil of resistance 20 Ω and inductance 300 mH is connected in parallel with a capacitor of 200μF. A variable frequency supply of 110 V is provided to the connection. Find the value of the frequency for the condition that the current drawn from the supply is in phase with the source voltage. Find the value of dynamic resistance and current for this condition
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).
