What does an arrow on an axial lead electrolytic capacitor mean?

The arrow always points to the negative lead.


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.


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 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).

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.


Should you worry about capacitor lead length in a circuit?

Capacitor lead length is a consideration in a circuit when the frequency involved is sufficient the make the parasitic capacitance and inductance of the leads important.


Do capacitors have internal resistance?

1. The capacitor has Lead resistance in series with the capacitor2. Since most capacitor use Dielectric and they have a leakage resistance and it is parallel to the Ideal Capacitor.


Why capacitor behave as open circuit against alternating current?

Capacitors store electrical charge. Imagine we have a capacitor. At time 0 seconds we connect a DC voltage across the capacitor - immediately as the voltage is connected the capacitor is at 0 volts and the maximum current (relative to the circuit resistance) flows. At this extreme the capacitor can be treated as a short circuit, so for high frequency AC volts we should treat a capacitor as being a short circuit. As time passes the current in the circuit will go down and the voltage of the capacitor will go up - this is because as the capacitor gains more charge it gains more voltage, lowering the voltage across any resistance in the circuit consequently lowering the current in the circuit. When the capacitor is virtually full no current will flow at all and the voltage across the capacitor will equal the DC source voltage. At this extreme the capacitor can be treated as an open circuit, so for low frequency AC (allowing the capacitor to fill up before the current alternates) we can treat the capacitor as being an open circuit. Technically, it is not an open/closed circuit when it comes to AC because the capacitance will results in a signal lag or lead. However, if the frequency is low/high enough the lag/lead is often negligable.


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.
