It can take (almost) any form, but what comes out of your wall is close to a sine-wave.

What is the visual representation of a voltage waveform?
Look up sine wave on Google to see a picture.
1 If the voltage applied across a capacitance is triangular in waveform then the waveform of the current is?
rectangular
Why clippers are also called limiter?
bcoz, voltage clipping limits the voltage to a device without affecting the rest of the waveform.
Why different frequencies has same average value and RMS value?
Voltage and frequency are independent quantities.AnswerBecause the r.m.s. value is dependent on the shape of the waveform, not its frequency. The average value of any symmetrical waveform is zero and is independent of frequency.
If the voltage applied across a capacitance is triangular in waveform then the waveform of the current?
Depend the value of capacitor. Capacitance in series act like a high pass filter, while in parallel act like low pass filter. By fourier series, triangular wave is combine of series of the sine or cosine waves. Therefore by certain capacitance, sine wave can preduce by applied a triangular signal through a capacitor. Current is just 90 degree shift from voltage, shape is same.
What is the visual representation of a voltage waveform?
Look up sine wave on Google to see a picture.
What is the physical length of a voltage waveform?
Voltage does not have a waveform. The waveform is based upon the frequency of the voltage or current. A battery (any voltage) does not waveform, however the voltage coming into your house (US) has a frequency of 60 Hz. The length of the 60 hz waveformLength (in centimeters) = (3 x (10 ** 10))/ Frequency in hz =500 000 000 cm
1 If the voltage applied across a capacitance is triangular in waveform then the waveform of the current is?
rectangular
What is difference between amplitude and peak value?
It is the highest value of the amplitude, called the peak value. Scroll down to related links and look at "RMS voltage, peak voltage and peak-to-peak voltage". Look at the figure in the middle below the headline "RMS voltage, peak voltage and peak-to-peak voltage".
Why do you obtain more dc voltage than ac voltage in power supply design by using transformer?
You don't. Transformers only work with AC voltage. Their input will be an AC waveform, and their output will be an AC waveform. Other electronics are used to convert the stepped down AC waveform from the transformer to DC.
How you can prove the Peak voltage?
Use an oscilloscope. That shows the voltage waveform and you can read the peak value.
What is the period of the voltage waveform out of a wall outlet?
60 seconds
Rate in which ac voltage waveform periodically repeats itself?
Frequency.
What is the power factor of a DC system?
It would be unity, or 1.0. Since the voltage in a DC circuit does not vary with time, there can be no phase displacement of the current waveform, and therefore the current could not lead or lag the voltage waveform.
Why clippers are also called limiter?
bcoz, voltage clipping limits the voltage to a device without affecting the rest of the waveform.
Why is average voltage of full wave rectified voltage different from the rms value of an equivalent ac waveform?
the number u are seeking is 0.639
What is the need for trapezoidal waveform for linearity correction?
This would keep the voltage across the inductance a constant, and corrects the non-linearity problem.
