i need 36V AC thus i seek for a 220-240V Ac to 36V AC transformer, but
the dimensions of the transformer should be like 16.5mmx16.5mmx11.4mm
(or close to those values). I think the members of the groups can help
me because i am unable to find it and i am not familiar with

I am looking for step by step instruction for calculating  the
efficiency of an induction motor (an ideally a breakdown of losses).
Can anyone help? I am particulary interested in exactly what to
measure, and how to correct for temperature in order to calculate the

I was wondering if someone could explain this to me. I'm not an
electrician, but am curious as to how this would work. I have 3 phase
power coming into a disconnect box. Basically 5 wires (Ground, Neutral,
L1, L2 and L3). I am going to have a battery backup system connected to

Hi All, I built a workbench over the weekend and since the garage has
limited outlet space I wanted to add a couple of outlets to it and feed
them power through a 12 guage extension cord.  I wired the outlets
correctly and the grounds are good and solid.  I plugged in the outlets

Does anyone know where I can purchase 3mm banana plugs in the UK ?.

Don,
Would you please give a solution to the following equation
for the response function (transfer function) of a driver
in a closed-box.

I thinking of developing a small microprocessor evaluation board for
use in the hobby/education market.
The unit is a single unenclosed PCB that will be powered via it's USB
interface. It will have a small amount of I/O for connection to 3V motors

We have often heard that people who are good survive at all times.
Unfortunately I am a mediocre. I am Arun from india. I will be

Thank you!

Hi there all,
I was wondering... I have a 3 phase transformer and I'm trying to find
the current on the secondary winding.
My transformer is 415 primary 50Hz - 208 Secondary 50Hz

Is there a way to measure how much electricity a computer is using?  It
doesn't need to be exact, just a guide.
Is it as simple as saying "if it has a 400W power supply then it uses 400W
per hour"?  Or is that just the maximum? is it per hour?

I would really appreciate any feedback regarding these calculators.

Can someone please advise as to the best company one would buy a
frequency - voltage converter to run my USA audio gear in Europe ? I've
heard of Major Power, Falcon among others but I need to deal with a
reliable company which makes a good product. I do have a budget of
