Well, electricity is a wicked thing.
All of it will transform 100.0000% in to heat.

To mix your brain a little more:
Electrical outlets have three wires L-GND-N
L=live
GND=ground
N=neutral

Electricity "waits" in the L when some machine that allows the electricity
to flow from L to N, like computer is plugged in.
The thing that is really mystifying is that the same current that leaves the L-wire goes to your computer and back along the N-wire.
So how is the electricity consumed?

Everything above is 100% true, just had to write it since this is being really foolish: yes but no, but yes but no chitchat.
