It is very nonlinear, like any forward biased diode. The higher the
current, the lower the resistance. I was assuming that the high
internal resistance of the double layer capacitor would dominate the
time constant.

No, this kid has distributed his homework questions into a couple of
threads, really if he doesn't even know how to answer these, he better get
out his textbook and study a bit, or he will have to repeat the class.

The glass is completely full - half with water and half with air.

What does that make me? ;-)

There is no practical example on that web page, and it surely does not
look like a simpler or faster way to design a transistor stage.

I once slapped together a textbook common-emitter amp because I
needed a quick-n-dirty mic preamp. I used a constant .6V B-E
drop and picked bias resistors based on beta, albeit swamped
out my expected base current by about a factor of 10.

Sorry if I did it "wrong", but I got it done in 10 minutes, and
it worked. ;-)

Cross posted to SED.

The proper answer is.

'How much is left in the bottle?'

Obviously, for non-engineers, this will lead to a discussion about the
relative levels of liquid left in the bottle.

However the engineer will consider factors such as,

'Have I got another one?'
'Is the shop still open?'
'Will this be enough?'
'Do I have the means required to aquire another one?'
'Perhaps I'll just go to bed.'

DNA

Those are good questions...

Another quip to doctor relatives is that there is a 'vas deferens' between
children and no children.

You could have at least disguised your questions into a less obvious form
that doesn't look like they came directly from your home work. For example,
you could have said: When I trigger my scope with an activated transformer,
smoke comes out of the intensity knob. What am I doing wrong? Then one of us
would be sure to answer.

My primary complaint about googlegroupies is that they forget to include
any context when they reply (or followup). googlegroups by default
doesn't include any context, so you'll need to copy/paste the context
that you're replying to.

Good Luck!

As you've already noted, anyone is pretty much free to post anything -
there is no "authorization" required, other than the google signup.

The thing is, those questions were just flagrant homework test
questions, and they are things that were already supposed to have
been taught in the class, or at least learned from the textbook.

In either case, just handing you the answer doesn't do anyone any
good - if you get an answer here, and just fill in the blank on
the test by these answers, then it's equivalent to cheating, and
you won't learn anything; and secondly, you run the risk of some
smartass posting completely wrong or misleading answers and
embarrassing yourself in front of your teacher and classmates.

Good Luck!

Rich,
Sometimes old bulbs or bulbs in a humid or corrosive environment develop a
cupric oxide film between the outer ring and the center terminal. This can
cause a small "leak" in current.
I was aware of what to do when my children and then later, grandchildren
developed a "leak". Perhaps this is why the bulb needs "changing". I think
now-a-days Pampers come in sizes from 25 watt to 150 watt.

Hi guys:

How does a wind-up generator (like in a wind-up radio) work? Is it
simply a dynamo that charges a NiCd battery, or is energy stored in a
power spring (or neither)?

Thanks for any replies.

Don

...Just to clarify. I realize that a power spring can't produce
electrical power. I just wondered if the mechanism truly winds up
(like a wind-up toy) and then this mechanical energy is converted into
electrical energy somehow.

I have a FreePlay radio with both wind-up and solar power sources.

The wind-up mechanism on this radio works like a clock. You wind the
spring and it drives a small DC generator (via a speed control
mechanism) to power the radio for about 30 minutes.

Other "wind-up" radios may have NiCad/NiMH cells and either use the
spring mechanism / DC generator to charge the batteries, or use a
crank-driven DC generator to charge the batteries directly (not
exactly "wind-up", but does use a hand-crank ;-)
