Electricity question |
Suppose I have 2 lights. One is 12 volts / 20 watts. The other is 120 volts / 20 watts.
Both run off of a regular electrical outlet. Obviously the 12/20 one has something internal to the light that converts from 120 volts to 20.
My question is, do they consume the same amount of electricity?

Is the 20 watts the light output rating, or the actual draw?
If it's draw, it's the same for both. If it's light output there's not enough unfo to answer your question

It's that stuff that comes out of the outlet and shocks you.

It depends on the transformer used doing the conversion to 12 volt.
As the transformer ages the power usage does increase.
With the right transformer they can be made the same.

Bulb choice is important as well. Are both light bulbs the same?

Converting 120 down to 12 uses electricity no matter how you cut it.
