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 value and peak to peak value of 12v?
All a.c. voltages are expressed in root-mean-square (r.m.s.) values, unless otherwise stipulated. So 12 V is an r.m.s value which, for a sinusoidal waveform, has an amplitude, or peak value, of 1.414 x 12 = 16.97 V. So its peak-to-peak value will be twice this amount -i.e. 33.94 V.
A sine wave with an RMS value of 100 v would have a peak value of?
For a sine wave ONLY - and assuming you are talking plus and minus 100V (200V peak to peak) - the RMS voltage is about 71V. (One half square root of 2 * single sided peak value)
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
Is AC voltage measured from Peak to Peak or from 0 to peak?
Both. When an AC voltage is measured and a number is reported, it is necessary to state that this number is rms value or peak value or peak to peak value.AnswerVoltages and currents are each normally expressed in root-mean-square (rms), unless otherwise stated. For example, when we talk about a '120-V service' or a '240-V service', we are expressing the voltages in rms values; it is unecessary to specify that these are rms values. For a sinusoidal waveform, Vrms = 0.707 Vpeak
Can a 230 V capacitor be used for a 440 V application?
Not all capacitors can be used for 220V; There are capacitors that are specially designed to withstand such high voltages.AnswerThe voltage rating of a capacitor is normally expressed as a d.c. value. If you want to use it on a 220-V a.c. system, then you must take into account that 220 V is an rms value, so you must determine its peak value. The peak value of 220 V (rms) is 311 V. So your capacitor must have a rated value in excess of 311 V d.c., or its insulation will fail.
If The wall outlet has RMS value of 120VAC what is the peak value?
220 V is rms in europe if that is what you are getting at. Peak is at about 311 V.AnswerUnless otherwise stated, all a.c. voltages and currents are expressed in r.m.s. values.

What value of resistor is required to convert 220 v c to 3 v dc?
There is insufficient information in the question to answer it. You need to specify something else, such as the resistance of the load.

When a light bulb is rated 100 w for 220 v supply. what is the resistance of the bulb and the peak voltage of the sources?
Ohm's Law: Resistance is voltage divided by current Power Law: Power is current times voltage Combining them gives: Resistance is voltage squared divided by power 220 volts squared divided by 100 watts = 484 ohms. Note that this is hot resistance. If you measure the bulb in the cold state, you will get an entirely different, smaller, value, due to the extreme temperature coefficient of the filament. Independently of that, since you ask for peak voltage, that means you are talking about an AC voltage source. We have to assume a sinusoidal waveform, and that the 220 volts was the RMS value. In this case, the peak value is simply the RMS value multiplied by the square root of 2, i.e. 0.707..., making the peak value 311 volts.
What affects the value of peak current?
From ohms law, I = V/R hence Voltage and Resistance can affect the value of current, both peak and average. Also with a rectifier circuit other factors can affect the peak current such as frequency and capacitance Craig - AUT

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.
Can an appliance of 230 V 10 A inert fuse be used in Australian domestic homes with 240 v power supply?
Yes, 240 volts is a "nominal" figure, related to peak current. The actual usable voltage is in the 220 -230 range and any 220-230 volt appliance will be quite happy.
