nt. For example, to find the wire required for 7 volts lossin a distance of 125 feet, with 21 amperes, we divide21 by 7, which gives 3; where the line of 3 amperes inter-sects the line of 125 feet, we are between the lines repre-senting No. 10 and No. 12 wire. The point lies aboutmidway between the… … < -LrloA 3NO JO doyQ 3AIO O- (AVM 3NO) -L33-J Nl HJ.0N3-] #- be borne in mind that lamps burning on lower voltages than110 take more current, and those burning on higher volt-ages take less current.
