Potential difference and power — practice question

The Atlantic torpedo is a sizable electric fish that can produce a voltage of $220\,\text{V}$ between its tail and its head. This creates a current pulse of $15\,\text{A}$ for a duration of $2.0\,\text{ms}$. The fish gives out $200$ pulses per second. Determine the average power output of the fish?

  • A$33\,\text{W}$
  • B$1.3\,\text{kW}$
  • C$3.3\,\text{kW}$
  • D$6.6\,\text{kW}$
