Is very small until triggered than will be appreciable when the sirens/lights are agoing!

19.a heat pump has a COP rating of 2.5 to 1. If 200 watts of electricity are used to run the heat pump, how many equivalent watts(heat) are produced?
A microscope is nothing more than magnifying lenses. Some of them use artificial light using electricity. Some microsopes use no electricity (zero watts) while a large electron microscope could use kilowatts.
As a rule of thumb 5-6 watts per person
About 3 kWh's of heat are created for every kWh of electricity it consumes
4000 watts on a 240 v system would be 4000/240 amps, 17 amps.

A lamp post produces exactly zero watts, just like my computer produces zero watts. It is a user of electricity, not a producer. The amount of electricity used will depend on the bulb that is used in the lamp post.
You are confusing electrical potential (Volts) and power (Watts). The equation for power (watts) is P = VI where V is volts (a measure of electrical "pressure") and I is current in amperes (the rate of flow of electricity). If the system is 120V and the power used is 600W then the current used is 5A. If the system is 240V and the power used is 600W then the current used is 2.5A.
On a 12-volt system 1.6 amps is 12x1.6 watts, 19.2 watts
None, the watts come form the electricity supply and the lamp uses them at a rate of 100 an hour when it is turned on.
300 Watts!
