Electrical engineering
In a Carey-Foster's bridge a resistance of 1 0125 2 is compared with a standard
resistunce uf l'0000 2, the slide wire has a resistance of 0'0250 2 in 100 divisions. The ratio arms
nominally each 10 N, are actually 10'05 and 9'95 2 respectively.
How far (in scale divisions) are tbe balance positions from those which would obtain of ratio
arms were true to their nominal value ? The slide wire is 100 cm lopg.
