An electric eel develops a potential difference of 460 V, driving a current of 0.75 A for a 1.0 ms pulse. Find the power of this pulse.

Explanation:
Power is the rate at which energy is transferred, given by P = V × I. With a potential difference of 460 V and a current of 0.75 A during the pulse, the instantaneous power is 460 × 0.75 = 345 W. The 1.0 ms duration would affect energy, not power: E = P × t = 345 W × 0.001 s = 0.345 J.
