Question

calculate power loss in electrical transmission cable,15 km long,carrying a current of 100 A 200kv.The resistance pr km of the cable is 0.2 ohm.

Answer 1

Explanation:

Given:

I=100

V= 200×1000

V=200000

. .

. D=15km

and resistance per km=0.2ohm

so, resistance for 15km=0.2×15

=3 ohm

so,

power loss by the 15km cable to transmit electricity=I×V×(R) of 15 km

=100×200000×3

=20000000×3

=60000000

=60000000/1000

=60000kwh
