A; AC. is a sinusoidal wave it has zero potential at some time and speed potential at its peaks. So overall the real effective value to do work is referred by this term. Effective.
The effective value of an AC = AC/√2. Example: the effective value of 8.5 V AC is 6.01 V, because 8.5/√2=6.01 Hope that helped :)
The amplitude (or peak value) of a 220 V AC voltage is approximately 311 V, calculated using the formula ( V_{peak} = V_{rms} \times \sqrt{2} ). The middle value, or average value, of a pure sine wave AC voltage is ( V_{average} = \frac{V_{peak}}{\pi} ), which is about 99.73 V. The effective (or root mean square) value is given as 220 V, which represents the equivalent DC value that would deliver the same power to a load.
With an AC and a DC voltage source in series, the DC voltage can be added to the RMS value of the AC voltage to give the effective voltage.
i think average value of current in ac current is zero.
virtual value=peak value/root 2 =707/1.414 =500
Effective = RMS= average Not for a sine wave it isn't. The r.m.s. value of a sine wave is 1.11 x the average, or mean, value. The "effective" value is not a term which I've seen in any of my reference books.

If the AC signal is sinusoidal, then the RMS value is 141 divided by square root of 2, i.e. 99.7 volts.
Yes, if it is set to measure AC, it is usually calibrated to RMS.

the answer is A effective
The rms value of a sine wave current is 0.707 Imax. So the answer to your quesion is 0.707 x 4 = 2.83 A.
EFFECTIVE HOW ABOUT AVERAGE .639 of peak.AnswerThe 'effective' value of an a.c. voltage (or current) is the same as its 'root-mean-square' (r.m.s.) voltage which, for a sinusoidal waveform, is 0.707 Umax.The 'average' value of an a.c. voltage (or current) is zero over a complete cycle, or 0.639 Umax, over half a cycle (usually applied to rectified waveforms).
Elgar AC's power supply are very effective for a variety of different reasons. Some of these reasons are they are cost effective and they have an IEEE-488.2 or RS-232 control.
i think average value of current in ac current is zero.
because power dissipated in ac is less than power dissipated in dc.
