A bird is standing on an electric transmission line carrying a large amount of current. Find the power dissipated by the bird If the

current it experiences is 1.35^-10 A which results in a potential difference of .0054V.

Side Note:
(I know the answer is 7.3 x 10^-11 W, I just don’t know how to get it)

Final answer:

The power dissipated by the bird is 7.29 x 10^-13 W.

Step-by-step explanation:

The power dissipated by the bird can be calculated using the formula P = IV, where P is the power, I is the current, and V is the potential difference. In this case, the current is 1.35 x 10^-10 A and the potential difference is 0.0054 V. Plugging these values into the formula, we get:

P = (1.35 x 10^-10 A) x (0.0054 V) = 7.29 x 10^-13 W

Therefore, the power dissipated by the bird is 7.29 x 10^-13 W.

P = 7.3 × 10^-13 Watt

Step-by-step explanation:

First of all, are you sure that what you have is the right answer?

Anyway, the definition of power dissipated is given by

P = I^2×R

where I is the current and R is the resistance. But we also know from Ohm's law that

V = IR

so we can rewrite the equation for power P as

P = I^2R = I(IR) = VI

= (0.0054 volt)(1.35 × 10^-10 A)

= 7.3 × 10^-13 Watt
