consider resis. /unitlength as a
radius = r
when angle at centre is 60*,
the length of minor and major arc are
r/3 and 5
r/3
resis. =
r/3*a and 5
r/3*a
they are in parallel
eff. resis = 5a
r/18 = R
when angle at centre = 90* ,the arc lengths are
r/2 and 3
r/2
resis. =
r/2*a and 3
r/2*a
they are in parallel ...effe resis. = 3ar
/8 = 1.35R
