Answer:
Conductance
Explanation:
The conductance of an object tells us how much that object is able to allow the flow of electric current.
Conductance is the inverse of the resistance, which tells instead how much the object is able to oppose to the flow of electric current.
Conductance is related to the resistance by the equation:
(1)
where
G is the conductance
R is the resistance
The resistance of an object is given by
where
is the resistivity of the material
L is the length of the object
A is the cross-sectional area of the object
Substituting into (1), we find another expression for the conductance:
which means that:
- The larger the cross-sectional area of the object, the higher the conductance
- The longer the object, the smaller the conductance
Answer:
0.333 i1
Explanation:
from figure
iB = i2
i1 = iA
i1 = iA = iB+iC = i2+iC
all resistances are equal o R
i1 = E/[R + 2R||R + R] = E/[8R/3] = 3E/8R
since if v is constant then i is inversely proportional to R
iB/iC = R/2R = 1/2
iC = 2iB = 2i2
and i1 = iB+iC = iB+2iB => i1 = 3iB = 3i2
thus i2 = i1/3
or
the equivalent resistance is
Req = [R || (R+R) ] + ( R + R)
Req = 2R/3 + 2R = 8R/3 ohm
current i1 = E / Req = E / ( 8R/3) = 3E/8R
i1 is divided in two parts as i2 = ib and ic
i1 is divided in i2 and ic in ratio 1 :2
Twice the current will flow through RC as will flow through RB and R2. So the current flowing in R1 and RA is divided by 3,
so i2 is 0.33*i1
i2 = [ 1 / (1+2) ] * i1 = 1/3 * i1
i2 = i1 / 3 = 0.333 i1
