If I have a power supply (not a computer power supply, just a battery-replacing wall wart) and it doesn't have the usual polarity marking, how to I know if the tip is positive or negative?
Update: I couldn't find my multimeter. I did find a model number...

That tells me at glance the polarity.
I mean it has a hardened tip already, why.
The point to etch the polarity symbol into the case, or label.

Hi All, I just came across this term "Polarity" and "Polarization" within the scope of Law of Attraction, Manifesting and Reality Creation. http://www.stevepavlina.com/blog/2007/02/polarity/ I seem to understand that this is something that trips people...

The choice is mine.
That you liked it :) @ Barry, thanks for the edit!! :) The energy polarity Steve Pavlin writes about polarity energy or incoming polarity energy.

I'm in the midst of redoing an old Philips CD player with caps and op amps.
I swapped out all the old caps including this 16V 6800 uf power supply cap using radial electrolytics. Reinstalled the board to test the machine and though it started fine, after...

Quote I'm hoping the damage is limited to the capacitor .
What does the top of the original look like?
The case almost looks like a bi-polar axial cap.

Hi;
I'm working on my Space Wars and have a Rev.A monitor.
I am replacing the film capacitors and have a concern regarding the
polarity. I was under the impression that they...

The symbols are interchangeable, the +
indicates polarity.

Film capacitors are non-polar.

I'm trying to make a basic circuit with a diode. Had it not been
marked "cathode/anode" I would have not been confused - I would've
just had the electrons follow the arrow...

For example, think of the diode symbol.
Schematic symbols
assume conventional current flow.

If you *really* can't identify polarity from the part, trace the circuit
back to the rectifier much confirms polarity.

What DOES vary sometimes.

At the risk of stating the obvious: many devices have a symbol
indicating the polarity that there is only one standard polarity
for 5v, but I would check the specs.
