How do you figure out how many watts a lamp post produces?
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.
If a lamp is off but still plugged in is it wasting energy?
No electricity can be used or wasted if the lamp itself is turned off. It makes no difference if it has been turned off at the wall outlet or at the lamp itself. It is the same situation as a flashlamp that has a light bulb supplied by a battery. If the flashlamp is switched off the battery inside it is still there, waiting to feed the light bulb with current, but the current can only flow into the light bulb when the switch on the flashlamp is turned on.

How many kilowatt-hours of electricity would be used by a 40-watt lamp that burned for 100 hours?
1 kW = 1000 w So 40 W / 1000 W = 0.04 kW As soon at the light is turned on, the lamp starts to use energy at the rate of 40 W = 0.04 kW. If you leave it on for 100 hours it will have used up 0.04 x 100 = 4 kWh

Does electricity continue to flow through a table lamp when the switch is on and the bulb is removed from the lamp?
Electricity flows by any conductor.But the most used to flow electricity is copper. Now if there is any problem with a wire even if it is a conductor the electricity will not flow.Sometimes when trying to make an electric circuit the electricity does not flow,if the wirehas no problem it is a problem with connection to make that work you just put silver paperbetween the 2 wires that have a problem in connecting to the bulb or any such thing.
