Answer:
Power does it draw from the mains = 2.78 kW
Explanation:
Power = Work / Time.
Here work done = Energy used by Bat taser = 2.5 MJ = 2.5 x 10⁶ J
Time taken = 15 minutes = 15 x 60 = 900 seconds.
Power = Work / Time = 2.5 x 10⁶/900 = 2777.78 Watt = 2.78 kW
Power does it draw from the mains = 2.78 kW
