Question

With the increase in the value of voltage and power factor, the cost of transmission line conduct

A.

Decrease 

B.

Increase

C.

is unaffected   

D.

increases exponential

Answer ( Option A)

Decrease 

Solution

In a power transmission line cross- sectional area of conductor is :

Loss

Therefore if the value of voltage and power factor of transmission line increase the cross-section area of inductor decrease and cost of transmission line is decrease.

Hence, the correct option is (A).
