Supposed you have a certain voltage and resistor values..
for example.. 110 volts and 55 ohms. The current would
then be 2 Ampere. Is there a way to boost the amperage
value to say 5 ampere without changing the voltage nor the

Hi Emma,
You've been asking a lot of slightly strange questions recently and I'm
beginning to get a little suspicious that you might be a troll. I'm very
sorry if that's not the case - I really wouldn't want to put you off if you

       --Have been all over the place, but can't seem to lay my hands on
an old centering joystick, analog variety with pots on it. In
desperation I went to a swap meet last weekend, but no luck. I've found
new ones for $200, but hey, these used to go for $5.- at C&H! Any leads

I'm looking for a User Guide for a Brother FAX-1700P combo
fax/phone/answering machine/copier. Tried Brother, but no longer
available. Copy (or scan) is fine - will gladly pay copying expenses.
Thanks,

Greetings, All
I have a tube which I would like to make the inside reflective.  
Does anyone know if there is a reflective type of spray or dip that I can coat the inside of the tube with
to give it a mirror type of coating?

  I'm trying to demonstrate the effects of Wireless Power Transmission
(WPT), but, I must be doing something wrong (or expecting the wrong
results). I'm using an NTE586, as a Schotkky Diode, I attach an LED across
the leads, and then hold it behind a 600 watt microwave. I don't see ...

Hi I own a 19inch auriga,just out of warranty,it is over scanning if I
scroll left  to right  I can see all the screen,all the writing is huge,I
dischared all the caps and HT ,and have tested every elec cap on the board
with no luck all test fine,no resistor look over heated,any ...

I'm doing an experiment on the effect of load. Does anyone
know what component to put or use so I can convert the
Sine wave from the AC outlet to square wave with no changes
in frequency? Something that can smear the rising amplitidue to

I'm in the UK and have a Shure EC11 bodypack transmitter with lavalier mike
on 174.8MHz. (I've also got an ECI transmitter on 173.8) I want to use this
pack with a camcorder so I need a portable receiver for the camera end.
Shure used to do a VP3 portable receiver for just this ...

In an Alternating Current system, the electrons oscillates back
and forth. In Power Inverters (where you convert DC to 110
volts AC), the output is just a sine wave.. meaning the
electrons don't really oscillate back and forth but only vary

Greetings All,
I'm looking for a place or how I can make some bolt adapters for a project?

This is my first post to alt.electronics. I have no formal electronics
training but have completed quite a few DIY projects ( Digital and Analogue)
from the net and elsewhere.
At the moment I am working on a Printerport (lpt) dac using the Quad 8bit

i have an ac volt meter (0-12v). i wish to use it to monitor pc psu
voltage across an led. I have tried it for 30s and it works, showing a
steady, 'non shacky' 4v reading. So, is using a ac volt meter for dc
volt reading recommmended ?.....

This is my first LCD and I am not having much luck.  I have checked over
my wiring many many times and cannot seem to find the problem.  It is a
4x20 hd4780 LCD.  When I turn it on the backlight comes on and I receive
the test signal, but some lines are missing.  The top 4 ...

Whether you have 100 Ampere or 0.5 Ampere, The drift
velocity of the electrons in a given wire is the same right?
So how does the electrons behave in high amperage vs.
low amperage.
