A power line with a resistance of 2 ohms draws a current of 80 A.The power dissipated in the line is
A)40 W.
B)160 W.
C)320 W.
D)12,800 W.
E)none of the above

Question

Quizplus · Accepted Answer

The power dissipated in the power line can be calculated using the formula:

Power = Current^2 x Resistance

Substituting the given values, we get:

Power = 80^2 x 2
Power = 12,800 W

Therefore, the power dissipated in the power line is 12,800 W, which is option D.
