If the inductance in an RLC circuit were larger, the phase angle between the voltage and current would increase, leading to a greater lag of the current relative to the voltage. This occurs because higher inductance increases the reactance of the inductor, causing the circuit to behave more like an inductor and less like a resistive load. Consequently, the overall impedance becomes more inductive, resulting in a larger phase angle.
What else can I help you with?
What will happen to phase angle if the the value of capacitor is increase?
in a series RC circuit phase angle is directly proportional to the capacitance
Why the phase angle between the generator voltage and the resistor voltage decreases as the frequency is increased.?
As the frequency increases, the reactance of inductive components in the circuit rises, which can lead to a greater phase difference between the generator voltage and the resistor voltage. However, in purely resistive circuits, the phase angle remains zero regardless of frequency. In circuits with inductance, higher frequencies can cause the inductive reactance to dominate, reducing the overall phase angle as the circuit approaches a more resistive behavior, particularly if the resistance is substantial compared to the inductance. Thus, the phase angle decreases as the frequency increases due to the diminishing influence of inductive reactance relative to resistance.
What happen to the phase angle if the value of capacitor is fixed and the value of resistor is changed?
The phase angle will either go up or down as well, depending on the new value of the resistor.
What IS power factor on 40VA 24VAC?
There is insufficient information in the question to answer it. You need some other information, such as voltage to current phase angle, inductance, capacitance, or watts. Please restate the question.
Why there is a phase shift of 30degree in Dyn11 3 phase transformer?
The phase shift is caused by inductance in the transformer. Any inductance from magnetic flux that fails to link both windings is called leakage flux, and the resulting inductance is called leakage inductance.

Why do you rate a dc machine in watt but a transformer in kilo volt-ampere?
The difference between watts and volt-amperes is due to the relative phase angle, or power factor, between voltage and current. In a DC system, the two are in phase. In an AC system, with only resistance, the two are also in phase. Add capacitance or inductance and the phase angle changes.

When current increases in an ac circuit what roll dose inductance play?
Inductance has no effect on the total current ... effective, RMS, amplitude, etc. ... in an AC circuit. It only affects the phase difference (angle) between the voltage wiggles and the current wiggles.
What is synchronous reactance?
Synchronous Reactance (in a generator analysis domain) is and equivalent series per-phase inductance term (think per-phase winding resistance) and is mainly composed of the machine's per-phase leakage inductance (equivalent series inductance of primary and secondary flux leakage) and armature reaction (distortion in flux introduced by an armature current in a machine, once again on a per-phase basis; described as a series inductance). L_SyncReac=L_leakage+L_ArmatureReaction. That sort of touches the surface of synchronous reactance.
What is the phase angle of a 30 ohm inductor in series with a 60 ohm resistor connected to a 5 khz souce?
The phase angle ( \phi ) in an R-L series circuit can be calculated using the formula ( \tan(\phi) = \frac{X_L}{R} ), where ( X_L ) is the inductive reactance and ( R ) is the resistance. The inductive reactance ( X_L ) can be calculated as ( X_L = 2\pi f L ). For a 5 kHz source and a 30 ohm inductor, the phase angle can be determined once the inductance value ( L ) is known. Without the value of ( L ), the exact phase angle cannot be calculated, but the relationship indicates that the phase angle will be positive, indicating current lags voltage due to the inductive component.
How do you convert j equations to phase angle equation?
The phase angle is the angle that has a tangent of (imaginary part)/(real part).
What happen when 220v dc is applied to a 220v ac single phase transformer?
The current would rise until it blows the fuse or breaker and that would produce an arc as the transformer's inductance tries to maintain the current.
What is the difference between phase angle and phase difference?
Although we use the term 'Phase angle' it's also an angle referred to another phasor (voltage or current).For example,conventionally when expressing power factor, we use 'voltage' as the reference. So the 'phase angle' of a particular phasor is the phase difference between our reference (voltage) & the phasor.As the gist, both mean the same except that 'phase angle' is the direction of the phasor w.r.t. positive x direction (reference)..AnswerBy definition, phase angle is the angle by which a load current leads or lags a supply voltage.Phase difference is the angle between any two electical quantities -for example, the angle two phase voltages of a three-phase system.
