Absolutely. The end of the body of the capacitor that has a radial indentation (like it was crimped) is the positive end. The manufacturers also color coat the ends, depending on the size of the capacitor. The black is the positive and the silver is negative. If you are doing an in-line installation (HID headlight kit, stereo, etc.), put the negative end of the capacitor where the source of current is coming from and the the positive end where it needs to go to. If the polarity is reversed, you may only get a momentary blip of power and then nothing at all. Just reverse the installation to correct it. Hope this helps. - mn1225

Which Capacitor should be connected in one direction?
The electrolytic capacitor should be connected in only one direction.
Why was the capacitor discharging current negative?
When a capacitor is discharging, current is flowing out of the capacitor to other elements in the circuit, similar to a battery. Current flowing out of an element, by convention, is defined as negative current, while current flowing into an element, such as a resistor, is defined as positive current. Thus a discharging capacitor will always have a negative current.
What is dc link capacitor?
when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .
Why initially capacitor taking more current?
Consider the instantaneous DC analysis. Initially, the capacitor has zero resistance. You apply a voltage and current is controlled by other resistive elements alone. As the capacitor charges, its effective resistance rises. This adds to the net resistance in the circuit, reducing current. At full charge, the capacitor has infinite resistance, so there is no current. Remember that the equation for a capacitor is dv/dt = i/c.
If we change the polarity of capacitor in ceiling fan why it starts rotating reverse direction?
by changing the polarity of capacitor of single phase ceiling fan can we change the direction of rotation from anticlockwise to clockwise
What is discharging direction of capacitor?
When a capacitor discharges the discharge current flows in the opposite direction to the current used to charge it.
Can a radial capacitor react different than an axial capacitor when being used as a filter for EMF?
Yes. The inductance of a radial capacitor can be different than an axial capacitor, particularly at RF, so the reaction as a filter for EMF could well be different.
Is a cathode positive or negative in capacitor?
Depending on the capacitor we are using it will have a cathode.For example if we take a unicapacitor(it will allow current on both sides) it will have a negative and a bi capacitor it will not have negative
What is axial thrust?
Axial Thrust is a force that is generated in an axial direction which is by definition along the shaft
What is axial direction in wood?
Axial direction in wood means its longitudinal direction (the height of the tree when it was growing). Engineers look at this as the direction that cylinder spins on its axis, if log were a roller, the axial direct ion would be along its length.
Can a resistor be installed backwards?
Resistors can be installed in any direction in a circuit. It doesn't matter in which direction you are installing a resistor. Resistor will resist the current in both sides of the connection. You can also apply capacitor in any direction for alternating current. Where as if you are concerned with direct current, a direction is needed to apply the connection
Axial flow turbomachines?
These are machines dealing with fluids, like (Axial Compressors, pumps and Fans). the term "Axial" is given due to the direction of inward and outward flow. In axial turbo machines the direction of outward flow is the same as the direction of the inward flow since the blades of the machines doesn't change the direction of flow.
What is the axial direction?
It is the direction in line with the axis of a member or structure
What is axial direction?
It is the direction in line with (parallel to) the axis of the part. If you have a cylindrical shaft, for example, the axial direction runs along the length thru the center of the circular ends.
Which Capacitor should be connected in one direction?
The electrolytic capacitor should be connected in only one direction.
What does an arrow on an axial lead electrolytic capacitor mean?
The arrow always points to the negative lead.
Why was the capacitor discharging current negative?
When a capacitor is discharging, current is flowing out of the capacitor to other elements in the circuit, similar to a battery. Current flowing out of an element, by convention, is defined as negative current, while current flowing into an element, such as a resistor, is defined as positive current. Thus a discharging capacitor will always have a negative current.
