What value exactly matches the rms value of an ac signal?
peak
Volts peak is equals to dc volts?
"Voltage peak" is generally used to denote the maximum(amplitude) of AC voltage supply. It can not be approximated as dc value. The closest approximation one can make for dc value of a ac supply is the RMS(root mean square) value of the voltage. So that the ohmic loss caused by the given AC voltage supply is equivalent to that caused by a dc supply having value equal to the RMS of this AC supply (for given impedance & time).
Which one of the following values exactly matches the rms value of an AC signal A.Effective B.Average C.Peak-to-Peak D. Peak?
the answer is A effective
The rms value of sinusoidal 200v peak to peak wave is?
You can work this out yourself. For a sinusoidal waveform the rms value is 0.707 times the peak value. As you quote a peak-to-peak value, this must be halved, first. Incidentally, the symbol for volt is 'V', not 'v'.
What is the peak value of a sine wave that has a peak to peak value of 60v?
30 volts provided zero crossing is at midpoint.

Household supply of 230volts is rms value or maximum value of voltage?
When you say holdhold supply of 230volts, you are referring to the RMS value, not the peak value.
What is the Relationship between the peak-to-peak DC voltage across RL and the peak input voltage in full wave rectifier?
The input voltage, an AC Sine Wave will have a Peak-to-Peak value equal to 2X its Peak value. Once rectified, all the Peaks will be either above or below the Zero reference line. They'll look like a series of identical bumps. The net value of the unrectified voltage will be Zero. The positive and negative waveforms canceling each other out. The rectified waveform will be all positive or negative and its net value will be non-zero. Its AVERAGE value will be .636 times its Peak value. Its Root Mean Square (RMS) value will be .707 times its Peak value. Its Peak-to-Peak value will equal 1X the Peak value.

AC or DC supply is given to a bulb which gives more illumination?
In AC supply, the RMS current is the effective current for power used in a resistive circuit. This is defined as the square root of the mean value of the square of the current, taken over a whole cycle. The RMS current dissipates power at the same rate as a DC current of the same value. A light bulb of course gives out light dependent on the current through the filament. So if the RMS current and the DC current are the same value, the light produced will be equal. With AC supply, the RMS value of current and volts is 1/(square root of 2) x the peak value, so peak value = 1.414 x RMS value. If you supplied DC at volts and current equal to the peak AC value, the power given to the light bulb would clearly be greater. Therefore to answer your question you have to specify what relative values your AC and DC supplies have.
Why is the peak voltage not exactly equal to the peak voltage of the alernating voltage and by how much it differ?
If you are referring to the voltage after the rectifiers in a powersupply, it is due to the voltage drop across the rectifiers.
What is a peak value?
Peak value is the highest value ever reached.
What is peak to peak?
Peak to Peak is the most positive peak to the negative peak value. Or find any peak value and multiply by 2.
Is Cathode ray oscilloscopes measure peak to peak value or average or root mean square value?
peak - peak.
