Question

The electrical resistivity of few materials is given below in ohm-meter. Which one of these materials has
the highest electrical conductivity?
A = 6.84 × 10-8
B = 1.60 × 10-8
C = 1.00 × 10-4
D = 2.50× 1012
E = 4.40 × 10-5
F = 2.30 × 1017​

Answer 1

Answer:

The answer is A

Step-by-step explanation:

because Resistivity directly proptional to Resistance

and heat increases with increase in resistance
