Question

the atlantic torpedo is a large electric fish capable of generating a voltage of 220V between its tail and its head. This drives a pulse of current of 15A lasting for a time of 2.0ms. The fish produces 200 pulses per second. What is the average power output of the fish? a.33W b.1.3KW c.3.3KW d.6.6KW

Answer 1

The average power output:
P = V * I * t
V = 220 V, I = 15 A;
t = 2 ms * 200 = 400 ms = 0.4 s
P = 220 V * 15 A * 0.4 s
P = 1320 W ≈ 1.3 kW
Answer:
b. 1.3 kW
