The one-drop rule is a social and legal principle of racial classification that was historically prominent in the United States in the 20th century. It asserted that any person with even one ancestor of black ancestry ('one drop' of black blood) 1 2 is considered black ( Negro or colored in historical terms). Drop 2 chord voicings are formed by taking a chord and then dropping the next to the highest note, or voice, to the lowest note of the chord. Similarly, there are drop 1, drop 3, drop 2 & 4, etc. Drop 2 voicings are important because most of these chords are easy for a guitarist to play on 4 adjacent strings.

| Use this calculator to estimate cable voltage drop forsizing conductors. The calculation assumes uncoated copper or aluminum conductorsoperating at the temperature selected and is based on the ac/dcresistance or impedance from NEC 2011 Chapter 9, Tables 8 and 9 for stranded conductorsoperating on a DC or AC 60Hz system. Rather than using the 'k' factor orthe 'Effective Z' of Table 9 this method is based on the actual ac resistanceand reactance values from the table. The load current input is fixed, as is thebase system Voltage. The Voltage drop in the cable is calculated using Ohm's Lawwhere Vdrop = Iloadx Rcable. The percent drop is Vdrop/ Vsystem x 100. For ac systems the acimpedance is used in place of the dc Rcable.This methodology is similar to the examples given after NEC Table 9. Theampacity of each conductor size shown for reference in the dropdown menu below is based on NEC2011Table 310.15(B)(16) for 60C insulated conductors rated 0 through 2000 volts with not morethan three current carrying conductors in raceway, cable or earth with anambient of 30°C (86°F). Exif editor 1 1 14. Note that the actual ampacity and voltage drop for yourapplication may differ from these results but in most cases will be very close tothose shown here. Units herein are American Wire Gauge (AWG) and English (feet). Note, to run this calculator JavaScripts must be enabledon your browser.

Nch software express burn plus 5 14 full crack. More information about voltage drop based on IEC standards is available in the Schneider Electric Electrical Installation Guide. | |
UPDATE: On 11/4/2009 the 3-phase %calculation was adjusted by a factor of 1.732 UPDATE: On 9/25/2013 added #16 AWG; ac values extrapolated UPDATE: On 4/27/2018 added 850V, 1000V and 1500V for dc solar systems UPDATE: On 10/16/2018 added 70V, 80V, 90V for dc systems UPDATE: On 02/25/2019 updated and added NEC references, expanded methodology description, added NOTE 4 and NOTE 5. UPDATE: On 4/3/2019 added more Voltage choices between 120 and 208 for dc solar systems |
