Short answer
House in US = 156V peak
House in Europe = 325V peak
Long Answer
AC voltages are usually identified by their RMS voltage. This is a mathematical calculation of the "average" or DC equivalent voltage. It is smaller than the peak voltage by a factor of about 0.707 for a sine wave AC which is the normal type.
The actual peak voltage in your house depends on a number of factors. The most important being what the nominal supply voltage is in your area.
The US typically uses a nominal voltage of 110V RMS = 156V peak
Most of Europe uses a nominal voltage of 230V RMS = 325V peak
Actual voltages in a particular house can vary significantly from nominal. Some specifications call for +/-10% from nominal. The difference is caused by voltage drops at various stages in electricity transmission. There can also be variations due to shortages of supply, etc.

When performing an AC analysis on a circuit which value of AC current should we use?
For calculations Peak or magnitude is used.
How do you change dc values to ac values?
To convert DC values to AC values if you are wanting RMS values they are the same. 100V DC and 100V AC (RMS) are the same "value". If you want to know the Peak-To-Peak AC value you would multiply the RMS value by 1.414. So 100V AC RMS equals 141.4 V Peak to Peak.
What is the peak to peak voltage for the AC line voltage in normal outlets of your house?
Peak - neutral for 120 volts RMS is 169 volts, or 120 * sqrt(2) Peak to peak will be 2 x this value, or 339 volts.
What value exactly matches the rms value of an ac signal?
peak
What is the virtual value of ac whose peak value is 707V?
virtual value=peak value/root 2 =707/1.414 =500
An AC has a peak value of 12 amps what is the average value of the current?
i think average value of current in ac current is zero.
A technician uses an oscilloscope to measure the peak value of an ac wave he tells you that the voltage has a peak value of 100v what is the rms value of the voltage?
100v divided by 1.41
Why you take 2Vm peak inverse voltage for full wave rectifier?
When the AC waveform goes to one peak, the capacitor that follows the diode is charged to that peak value. When the AC waveform goes to the other peak, the same diode is reverse biased between the alternate peak value and the charged value of the capacitor. This differential voltage is two times peak voltage.
What is the peak-to-peak voltage in a circuit with an rms voltage of 120VAC?
ANSWER: The peak to peak voltage can be found by multiplying 120 v AC x 2.82= 339.41
Why it is useful to use rms notation for alternating current and voltage?
AC waveform is sinusoidal waveform it has both positives and negative cycles so we dont have a standard constant value to do Measurements so instead of using AC quantities we use ROOT mean square values which is obtained by dividing Vpp(peak to peak voltage) by 1.414AnswerThe rms-value of an AC current is the same as as the value of DC current that will do the same amount of work. For example, 10 A (rms) AC will do exactly the same amount of work as 10 A DC.
What is the effective value of an AC signal of 141 volts peak value?
If the AC signal is sinusoidal, then the RMS value is 141 divided by square root of 2, i.e. 99.7 volts.
Is 240v rms value or peak value for AC source?
rms. dat means Vp-p will be 325V.
