How is positive lead on an electrolytic capacitor identified?
Normally all electrolytic capacitors negative lead is marked on the side and if the plastic cover came off and it is new the long lead is the positive.
Difference between electrolytic axial and radial capacitors?
Difrence is between lead positions. Axial one is -[]- and Radial =[] Axial ones are mutch pricier, but they are good choice for poin to point construction and low profile pcb's.
How can you identify the positive leg and negative leg on an Electrolytic capacitor?
The positive leg is usually indicated with a red dot. Sometimes there is an white arrow that looks like a minus sign - that is the negative terminal. If it is a can type, the can is the minus terminal and the tab(s) is(are) the plus terminal(s).
What is capacitor LS?
The distance between the leads (lead spacing) on a radial capacitor
Can capacitor store charge from ac source?
Yes. A capacitor stores charge from any source, including AC.The difference between DC and AC, however, is that the capacitor will be constantly changing in charge, in step with the AC. Due to the nature of the capacitor, the current through the capacitor will lead the voltage by some amount, depending on capacitance and resistance. {In the ideal case of a perfect capacitor, conductors, and AC power source, the current will lead the voltage by 90 degrees phase angle.}This is called capacitive reactance.Another way for a capacitor to store charge from an AC source, of course, is to place a rectifier diode in front of the capacitor. This, then, becomes an AC to DC converter.

Now do I identify which lead on a electrolytic capacitor is or - There is a short and long wire?
See web site http://www.stsi.biz/eeu-fc0j272l.html The short lead is the negative side.

What is the ohm rating of a 10v 330uf electrolytic capacitor?
Capacitive reactance is -1 / (2 pi f C), so the reactance of a 330 µf capacitor at 60 hz is -8 ohms. (The negative sign simply means that the current will lead the voltage.) However, an electrolytic capacitor is not designed for operation on AC, as it can only have voltage applied to it in one direction only. The equation still holds, however.
How do you find the polarity of capacitor wikianswerscomQHow do you find the polarity of capacitor?
To determine polarity in CAPACITORS:Electrolytic capacitors are often marked with a stripe. That stripe indicates the NEGATIVE lead.If it's an axial leaded capacitor (leads come out of opposite ends of the capacitor), the stripe may be accompanied by an arrow that points to the negative lead.Sometimes, you can look to the length of the leads as an indication of polarity. The positive lead is usually longer but be careful if you're reusing old or 2nd hand capacitors - the leads may have been trimmed.Tantalum capacitors are often marked with a '+'sign.http://www.westfloridacomponents.com/polarity.html
What is capacitor LS?
The distance between the leads (lead spacing) on a radial capacitor
What is an axial lead resistor?
It's a resistor where the leads (wires) are axial (they come in at the center of each end of the resistor).
What is the difference between radial displacement and axial displacement?
Hey, the difference is quite clear! Radial is the distance between the two shaft axis and is quantified by measuring the radial distance between the centerline of one shaft if it were to be extended to overlap the other, but Axial misalignment is the variation in axial distance between the shafts of the driving and driven machinery. Good luck honey...
Who is the head of the Circuit Court?
The Lead Capacitor
How are capacitors polarized?
A polarized ("polar") capacitor is a type of capacitor that have implicit polarity-it can only be connected one way in a circuit. The positive lead is shown on the schematic (and often on the capacitor) with a little "+" symbol. The negative lead is generally not shown on the schematic, but may be marked on the capacitor with a bar or "-" symbol. Polarized capacitors are generally electrolytics.
How do you charge a capacitor?
You charge a capacitor by placing DC voltage across its terminal leads. Make sure when using a polarized capacitor to place positive voltage across the positive lead (the longer lead) and negative voltage across the negative lead. Also make sure that the voltage you charge the capacitor to doesn't exceeds its voltage rating.
