A cable of resistance `10 Omega` carries electric power from a generator producing `250 kW at 10,000 V`. The current in the cable is

A

`1000 A`

B

`250 A`

C

`100 A`

D

`25 A`

Text Solution

Verified by Experts

The correct Answer is:
D
`P = VI or I = (P)/( V) = ( 250 xx 1000)/( 10000) A = 25 A`
