Power Consumption?

I want to know the power consumption of the appliances; both the appliances work at the 220V mains.
Both the appliances excite at 50mA input current. I want to know how much power each of them consume. The latter is an electronic gadget that has zener diode to drop down to 10V .

Here's the diagram:

Since both of them work at 220V main i feel its 50mA * 220 V > Thats what goin to be read in Domestic Energy Meter at every Home. Am i right? If wrong Give me a Justification...

Electric light bulb = 220 X 50ma Transformer (gadget) line side same as bulb, secondary side = 10 X 50ma Hope this helps Jim
 
No, dont add the secondary current, I was saying thats how the secondary circuit will draw current. See example below:

100V primary for a 100VA transformer will draw 1.0 amp on the line side.... BUT,,, when I am deciding how much a 10V secondary can provide me it would be: 100/10 or 10 amps. The higher voltage the less on the primary. For your project your drawing 100ma dont add the secondary. Jim
 
Doubt ~ A transformer changes voltages. i.e 220V to 10V maybe its not a transformer, I dont know what you have there. works the same tho.

I'm actually confused with power consumption in Primary and Secondary... So i request you give me the answer for the example discretely?
( Like Electric Bulb : Primary> **** Secondary : *****
Gadget : Primary > **** Secondary : *****)

Why it is so; How the energy meter shows only to 10V DC. Where does 220V AC go?
