Why The Excitation current is non-sinusoidal when applied voltage is sinusoidal?
excitation voltage is sinusoidal because it is taken from the terminal of alternator but excitation current is non-sinusoidal because it always dc.
What is firing angle in thyristors?
A sinusoidal AC waveform is divided up into 360 degrees, with the positive half and the negative half of the waveform combined into a kind of circle. The firing angle simply refers to the point on the waveform, as measured in degrees (thus 'angle') which the thyristor is triggered into conduction. Answer2: Firing angle is the phase angle of the voltage at which the scr turns on. There are two ways of turning an scr on..one is by applying a gate current or by applying a voltage across the scr until it becomes greater than the breakover voltage.... Answer3: Thyristor need gate current and voltage to make it conduct. The firing angle is the sinusoidal increasing voltage. As it rises a voltage is reached with enough power to fire to trigger the gate. That voltage is the angle considering that a sinusoidal is 360 degrees per cycle.
What is a sinusoidal AC waveform?
Its actually a sine function graph. It illustrates the variation of voltage and current with time. Yeah voltage varies every second in your house, only reason you cant detect it is the high frequency( >60 hz) at which they are transmitted.
1 If the voltage applied across a capacitance is triangular in waveform then the waveform of the current is?
rectangular
What is maximum current?
If you are referring to an a.c. current, then the maximum current is the amplitude of its waveform. For a sinusoidal waveform, the amplitude of an a.c. current is its root-mean-square value, divided by 0.707. For example, an a.c current with an rms value of, say, 10 A will have an amplitude of 14.14 A,

What is not true of sinusoidal current?
Sinusoidal current is not true of sinusoidal current.
What are the attributes of a sinusoidal waveform?
Amplitude, frequency/period and phase.
What is alternating current produced by?
Alternating current is produced by generators or power plants that use magnetic fields to induce voltage and generate electricity. This type of current changes direction periodically, typically in a sinusoidal waveform.
What is RMS value of an AC Sinusoidal Waveform and the power they carry?
Hi, RMS is voltage X .707 and the power is voltage X current. Hope that helps, Cubby
Why sinusoidal load is prefer over square load?
Sinusoidal loads are preferred over square loads primarily due to their smoother waveform, which results in less harmonic distortion and reduced stress on electrical components. This leads to improved efficiency and lower heating in both the load and the power system. Additionally, sinusoidal loads facilitate easier analysis and control in AC systems, making them more compatible with standard power generation and distribution methods. Overall, they enhance system reliability and performance.
What is the wave form of clipping circuit?
As a sinusoidal signal is clipped the waveform approaches a square wave.
What is the waveform of AC through a straight wire?
Either sinusoidal, or can always be represented as a sum of sinusoids.
What angle is the voltage or current is momentarily constant?
In an alternating current (AC) circuit, the voltage or current is momentarily constant at the peak of its sinusoidal waveform. This occurs when the waveform reaches its maximum or minimum value, resulting in a momentary pause where the rate of change is zero. At these points, the angle of the waveform corresponds to 90 degrees (π/2 radians) or 270 degrees (3π/2 radians), depending on whether it is at the positive or negative peak, respectively.
Would a sinusoidal input to the comparators produce the same transfer curve as a triangle waveform?
No, a sinusoidal input to the comparators would not produce the same transfer curve as a triangle waveform. A triangle waveform has linear rising and falling edges, which results in a symmetrical and predictable output when compared to a threshold. In contrast, a sinusoidal input varies continuously and smoothly, leading to a different output behavior as it crosses the comparator thresholds. Therefore, the resulting transfer curves will exhibit distinct characteristics based on the shape of the input waveform.
What is sinusoid?
What is a sinusoidal wave? This is a wave that appears to have curves. AC current/voltage. If you see a wave on a ossiloscope of what our AC (Alternating current) mains voltage that will be the answer to the question. DC (direct current) does not appear to have the same qualitys
