The above diagram shows the impedance triangle. The base of this impedance triangle representsresistance. The resistance is independent of frequency; so, if frequency increases or decreases, resistance remains constant. The formula for inductive reactance is XL= 2πfL. So, if frequency increases, in...
RLC Circuit For drawing the phasor diagram of series RLC circuit, follow these steps: Step – I.In case of series RLC circuit; resistor, capacitor and inductor are connected in series; so, the current flowing in all the elements are same i.e Ir= Il= Ic= I. For drawing the phasor dia...
Impedance Triangle in RLC series circuit: The total impedance of an RLC series circuit can be found using an impedance triangle. First of all, we have to consider the resistance and reactance of each component and then put them into the impedance triangle to find the total impedance of the R...
The series RLC circuit is now referred to as capacitive and the phase diagram for this situation is shown in Fig. 2.2c. EXAMPLE 2.1 If the voltage source in Fig. 2.2a is changed to ν(t) = Vp cos(ωt+ϕ), find the current i(t) in the circuit. First, let us convert the ...
Phasor Diagram 1.9.5 Phasor Voltage–Current Relationships of Circuit Elements Voltage v(t) and current i(t) are sinusoidal signals at a frequency of ω rad/s, whereas V and I are phasor voltage and current, respectively. The v–i and V–I relations for R, L, and C elements are ...
After a few roundtrip reflections, TWs recombine into stationary waves, and the power system starts to look like a lumped parameter RLC network in a transient state. The protection system can analyze the "lumped circuit theory" transient waveforms and reliably operate in milliseconds. Incremental ...
Converting a phasor back into the time domain allows us to obtain the time-domain representation of a circuit, which is necessary for calculating values such as voltage and current. This simplifies the analysis of AC circuits, as it reduces the number of equations and calculations required. Are...
