The time taken for a surge to travel a 600 km long overhead transmission line is
Right Answer is:
0.002s
SOLUTION
The time take for the surge to travel distance T =(L/v) second
Where
L is the distance
v is the velocity of the surge which is equal to 3 × 108 m/s
The distance given is 600km which is equal to 6 × 105 m
T= (6 × 105/ 3× 108 ) = 0.002 s
