i...HELLO HUMPHERY<br />thank you so much for reply me . <br />i fully understood that rms voltage means that:<br />the ac voltage that has the same heating or working value as dc <br />for getting the peak we have to multiply the amount of rms to 1.414 and this number is root of no 2 and this is mathematics and formula<br />in Kabul the working voltage is 220 <br />thanx<br />behbehzadhttps://www.blogger.com/profile/05844676726383148062noreply@blogger.comtag:blogger.com,1999:blog-1120987647049297737.post-39475059972822124932010-10-11T13:05:04.190+03:002010-10-11T13:05:04.190+03:00Good question, here we are talking about basic ele...Good question, here we are talking about basic electricity Beh, an example is worth a thousand theories.<br />Suppose you are buying electricity from two companies A and B.<br />Company A says it will supply you with 100 Volts Direct current (DC)<br />Company B says it will supply you with 100 Volts Alternating Current (AC)<br />For me I will have no problem with company A because for direct current it is straight forward-he offers to provide 100 volts just like you would get from a Battery.<br />But I will have some questions to ask company B, you know Alternating Current(AC) has a sinusoidal wave which moves from zero volts, up to positive peak(+) back to zero again, down to negative Peak(-) and the cycle continues. So it would be wise to ask if the 100Volts it is providing is peak or mean. ? If they are providing you with peak then it means you will be getting that 100Volts only briefly in every cycle.<br />To get the equivalent of 100 Volts Dc (R.M.S) we multiply 0.707 X peak (Vac)<br />R.M.S = 0.707 X Peak<br />Make Peak the subject<br />Therefore :-<br />Peak= R.M.S/ 0.707<br />Or Peak = R.M.S X 1/0.707<br />But 1/0.707=1.414<br />Therefore Peak = R.M.S X 1.414<br />Oh! This figure 1.414 happens to be the square root of 2, hence the name root mean square….<br />If you take your meter and measure the voltage at your power socket in your house you find it will around 110 volts AC in USA or 220 Vac in other countries like Kenya, Britain, and Australia etc.<br />This voltage on your meter is in R.M.S (root mean square) or equivalent effective value<br />The Voltage you get at the main Capacitor is actually the peak voltage of the supply outlet.<br />So for countries using 110 Vac( rms) this will be 155 vac peak and for countries using 220 volts ac this will be around 311 vac.<br />Hope I have answered your question Beh, you can also google basic electricity for more info.<br />By the way Beh, in your country do you use 110 Vac or 240 vac?<br />Regards<br />HumphreyHumphrey Mndakahttps://www.blogger.com/profile/11910022657325511431noreply@blogger.comtag:blogger.com,1999:blog-1120987647049297737.post-38902865189916532052010-10-09T20:15:52.360+03:002010-10-09T20:15:52.360+03:00HELLO HUNPHERY
