| X.2814 X 2814 - SECOND REMY 6 CYLINDER COIL (Model 284A). Impedance of primary = 6.5 volts / 2.6 amps. = 2.5 w. Resistance ditto = 4 volts / 4.4 amps. = .91 w Reactance = √6.25 - .83 = √5.42 = 2.33 w L = 2.33 / 262 = .0089 henry. Primary resistance = 1.6 volts / 1.65a = .97 w Ballast = 6v / 1.65a = .36 w | ||
