An electric eel develops a potential difference of 470 V , driving a current of 0.85 A for a 1.0 ms pulse. A. Find the power of this pulse.
B. Find the total energy of this pulse.
C. Find the total charge that flows during the pulse.

(a) The power of this pulse is 399.5 W

(b) The total energy of this pulse is 0.3995 J

(c) The total charge that flows during the pulse is 8.5 x 10⁻⁴ C

Explanation:

Given;

potential difference developed by the eel, V = 470 V

current, I = 0.85 A

time, t = 1 ms = 1 x 10⁻³ s

(a) the power of this pulse.

P = IV

P = 0.85 x 470

P = 399.5 W

(b) the total energy of this pulse

E = Pt

E = 399.5 x 1 x 10⁻³

E = 0.3995 J

(c) the total charge that flows during the pulse

Q = it

Q = 0.85 x 1 x 10⁻³

Q = 8.5 x 10⁻⁴ C

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
