What is the effective value of 200 volts peak-to-peak?
200 volts peak-to-peak is 100 volts peak, which is 70.7 volts rms (standing for root-mean-square) also called "effective". This 70.7 volts is the DC voltage with the same heating power as the peak-to-peak. The relationship is: rms (aka RMS) equals peak-to-peak divided by 2, then divided again by square-root of 2 (1.414). The division by 2 gets us from peak-to-peak to just peak. The next division takes us to rms. If you get an AC voltrage with no description, for exmple 120 volts AC, it is RMS (effective). The USA AC standard supply voltage is 120 (also called 117) volts RMS. The USA peak is 117 x 1.414 (square root of 2) = 165 volts peak, = 330 volts 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.
Rms value defination?
Because alternating current (AC) voltage varies over time, to the positive and negative, an actual AC voltage measurement will not be the same as a DC voltage measurement. For example: 5 volts DC is 5 volts constantly, viewed over time. The average voltage is 5 volts. 5 volts AC (from zero to peak) is not actually 5 volts constantly, but varies between 5 volts and 0 volts over time. The average voltage will not be 5 volts. Using RMS AC values is designed to make AC and DC measurements equivalent, for example 5 volts DC and 5 volts RMS AC are almost identical.
How many VAC equals a KVA?
VAC means volts AC, and is a measure of the voltage in an AC circuit.KVA means kilovolt-amperes, and is a measure of the power in a circuit. For a resistive load, KVA is the same as KW, or kilowatts.The two terms are not related in that you can not compare one to another without also knowing the current flowing in the AC circuit. VAC * IAC = KVA, when all values are in RMS (not peak to neutral or peak to peak quantities).
What voltage of an ac circuit has a peak voltage of 396 volts?
Approx. 280 VRMS. Vpeak * 0.707 = Vrms

Is 12 volts dc as powerful as 120 volts ac?
You get power by multiplying the amperes and the voltage. 12V, 10A dc would give the same power as 120V, 1A ac.
Why AC is dangerous as compare to DC for same amount of voltage?
The danger is in the voltage, not if it is ac or dc. For instance, 12v dc or 12v ac makes no difference in body contact. Neither will shock you. Usually 24 volts will not shock either. When you get to 48 volts or greater, then you have a chance of shock. 100 volts Ac or Dc shocks basically the same. 120 volts AC is actually 144 volts peak to peak, so 120 volts AC is slightly worse than 120 volts DC. Amperage is actually what kills. A "Taser" voltage can be as high as 50,000 V but the amps are so slow that it doesn't do permanent damage. Commonly people are shocked accidentally by a spark plug wire on a car or a lawnmower with no lasting or ill effects. This voltage can range from 15,000 volts to more than 50,000. These systems have very low amperage.
Why 440 volts running capacitor if my ac is 230 volts?
The 440 volts listed on the cap is the maximum allowable voltage the capacitor can handle. You could actually use a 370 volt cap on 230 volts. ANSWER; 230 volts AC can it actually be 644 volts peak to peak . It is 44ov because it must be rectified and sees only 324 volt peak which is withing the 440 volt capacitor handling voltage
How do you calculate the ac amps when you have the DC volts DC amps and the ac volts?
the answer is dc volts are rectified from ac volts and the amperage will be the same unless you account for the slight drop from the rectifier. dc volts from a battery have no relationship to ac volts. you can derive ac volts from a dc source using an inverter.
Is a converter considered ac out put volts?
is an 120 volt ac converter that we are using for 12 volts considered AC output power.
How do you reduce 12 volts to 3.7 volts?
If the voltage is AC a transformer can be used.

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.
Can a 220 volts ac fan run in a 12 volts battery?
No, a 220 volts AC fan cannot run directly from a 12 volts battery. The fan requires a much higher voltage to operate efficiently. You would need a power inverter to convert the 12 volts from the battery to 220 volts AC to power the fan.
