The equation for the average over time T is integral 0 to T of I.dt
There is no such thing as a d.c. transformer; all transformers work on a.c. So, what you are probably referring to is a power supply: the type of thing you would use, for example, to run a small radio or to charge a battery. In that case, no, you cannot plug a a.c. appliance into a power supply that has a d.c. output.
You have not provided enough information. For 12 volt peak to peak, purely AC signal, there will be no DC (hence purely AC). This means there is no offset - the AC signal peaks at 6 volts and -6 volts. The RMS value of this is VRMS = peak / sqrt(2) = 6 / 1.4.
rms value of ac power = dc power in reference to heat production in pure resistive load So ac power of some rms value will produce the same heat in resistive load as dc power will of same value
Many can measure both - Vrms (AC) or DC voltage.
theperpose of a power supply is to step up or step down an ac voltage to a desired dc value
equation of ac machine
Yes. the mean is the average. Since DC is a constant, stable output, the average = the DC magnitude. The average of 1 = 1.
so far i knew, the transformers are used to seprate dc component from ac component of supply fed into primary winding of coil. still if dc output value of ac input has to be calculated then it is v2*2/sqrt(pi) where v2 is peak ac output voltage and is equal to v1*n2/n1 pi is a constant numerically equal to 3.14 thus the dc value is average value of output ac voltage -------------------sachin_the_rex@aol.in------------------------------
no, dc volatage is a type of current direct current, ac is alternating current, average voltage could be any type of voltage ac or dc that maintains a constant rangeAnswerNo. A DC voltage is exactly equivalent to an AC rms-voltage. So, for example, 100 V (DC) is exactly equivalent to 100 V (AC rms). The average value of an AC waveform is zero.

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.
DC, as in Direct Current? then its Amps. xxtwilightxx
No. The value and polarity are different.

first it converts ac to dc as rectifier But the required dc voltage is obtained by taking average of on & off DC input voltage.
DC
RMS current is converted to DC current by using a rectifier. Capacitors and other components are used to make a cleaner DC output with less ripple.
