Question

Two copper conductors have equal
length. The cross-sectional area of one
conductor is four times that of the
other. If the conductor having smaller
cross-sectional area has a resistance of
40 ohms the resistance of other conduc-
tor will be
(a) 160 ohms . (6) 80 ohms
(c) 20 ohms (d) 10 ohms​

Answer 1

Answer:

d

Explanation:

the cross sectional area is inversely proportional to the resistance.
