An electric ell develops a 450V potential difference between its head and tail. The eel can stun a fish or other prey by using this potential difference to drive a 0.80 A current pulse for 1 ms. What is the energy delivered by this pulse and (b) what is the the total charge that flows?

Given Information:

Potential difference = V = 450 V

Current = I = 0.80 A

time = t = 1 ms = 0.001 s

Required Information:

(a) Energy = E = ?

(b) Total charge = q = ?

(a) Energy = 0.36 J

(b) Total charge = 8x10⁻⁴ C

Explanation:

(a) What is the energy delivered by this pulse

The energy is given by

E = V*I*t

Where V is the potential difference, I is the current flowing and t is the time.

E = 450*0.80*0.001

E = 0.36 J

(b) what is the the total charge that flows?

We know the current is the rate of charge

I = q/t

q = I*t

q = 0.8*0.001

q = 0.0008

q = 8x10⁻⁴ C
