Question

An electric eel develops a potential difference of 450 V, driving a current of 0.80 A for a 1.0 ms pulse. For this pulse, find (a) the power, (b) the total energy, and (c) the total charge that flows.

Answer 1

Answer:

a) 360W

b) 0.36 J

c) 0.0008 C

Explanation:

1 ms = 0.001 s

a) The power is the product of current and potential difference

P = VI = 450 * 0.8 = 360 W

b) The energy is the power multiplied by time duration

E = Pt = 360*0.001 = 0.36 J

c) The total charge is the current multiplied by the time duration

C = It = 0.8*0.001 = 0.0008 C
