Verified answer
Diket :l = 45,3 km = 45.300 m
d= 14 mm
rho = 0,017 ohm mm2/ m
dit :
Hambatan kawat ( R )
jawab :
#hitung jari" dl :
r = 1/2 . d
r = 1/2 . 14
r = 7 mm
#lalu hitung luas penampang:
A = phi . r^2
A = 3.14 . 7^2
A = 153,86 mm
# hambatan :
R = ( rho . l ) / A
R = ( 0,017 . 45.300 ) / 153,86
R =770,1 / 153,86
R = 5 ohm
