on an LED, the negative end is the shorter side.
on a capacitor, the negative end usually has some kind of marking on it, whether its a line, or an arrow or something.
with ceramic disk capacitors, there is no negative end, you just attach each side to a positive end, usually for a solar panel or something to store energy.
What else can I help you with?
Do electrolytic capacitors generally have polarity?
Yes. Electrolytic capacitors are polarized. Capacitors with positive and negative poles generally have positive and negative marks. Generally, for capacitors with pins, the long end of the pin is the positive electrode. For cylindrical electrolytic capacitors, there will be a vertical line printed on the negative side of the capacitor. SMD capacitors generally have no positive and negative poles. --- We're JYH HSU(JEC) Electronics Ltd (or Dongguan Zhixu Electronic Co., Ltd.), an electronic components manufacturer.

What is a padder capacitor?
Padders are a type of Capacitors which are used at low frequency end of the radio dial.
How do you tell what end is positive on capacitor?
there are a number of different types of capacitors, each with its own identification. on common electrolytic capacitors the negative terminal is shorter and the side with the negative terminal is marked with a white line. note that ceremic capacitors are bipolar. ie. it doesnt matter which way they are connected. thse are shpaed like a bean and are commonly brown or green. if in doubt look up the data sheet for the component. just type in the identification on the capacitor into a search engine.
In an electric circuit why do the electrons go from the positive side of the battery to the negative side?
The short answer is that they don't. But that doesn't help you much. Electrons flow from the negative terminal to the positive terminal. Why? Negative and positive (opposite) charges attract each other, and like charges repel each other. So you can think of the positive charged end pulling electrons towards it, as well as the negative charged end pushing electrons away from it. Water makes a good analogy, the battery is a pump, so there is high pressure on the outlet of the pump ( the negative terminal ) through the pipes and whatnot, ( the wire and whatnot) to the inlet of the pump ( the positive charged end ).
Why would a 63 amp fuse holder get hot?
The only time that fuse holders gets hot is when there is a loose connection between the fuse holder and the wire connected to the holder. If this is happening remove the supply voltage from the circuit that the fuse holder is in. Remove the wire from the holder. Cut the burned end of if there is enough wire and re install. If not enough wire, use a wire brush to get the oxidation off of the wire. Apply a coating of anti oxidation compound on the wire end and then re install into the holder. Tighten the wire into the holder very tightly. Check the spring clamping pressure of the fuse end of where the heating occurred. This spring clamping pressure is important for low resistance conductivity. If the fuse feels loose when installed change the fuse holder for a new one.
How do you determine which wire on a solar panel is the negative end?
The negative wire on a solar panel is typically marked with a black color or minus (-) sign. You can also use a multimeter to test the voltage output of each wire to identify the negative end.
Why the capacitor broke?
You probably put the negative end in to a positive power source. Did you enjoy the fumes?
Which end of a battery goes against the curly wire for musical clock?
Negative
What do i do with the ground wire on my sony CD player?
You "ground" it or connect it to a negative source that is connected got the negative end of the battery
How would you build an elctromagnet?
get an nail wrap insulating wire around the nail( the more times you wrap it, it stronger it is), then connect one end of the wire to the positive end of a battery and the other to the negative end.
How do you remove a capacitor from a circuit board?
Correct method:Two pieces of equipment are needed. A small wattage soldering iron and a desoldering tool. Heat the junction point up until the solder melts. Use the desoldering tool to remove the melted solder. Do the same thing to the other sideof the capacitor by heating and removing the solder. The capacitor should nowpull away from the PC board.=====Lazy method:--One piece of equipment is needed. A small wire cutter.-- Select one end/side of the capacitor. Position the jaws of the tool oneither side of the wire emerging from it. Then cut.-- Position the jaws of the tool on either side of the intact wire emergingfrom the opposite end/side of the capacitor. Then cut.-- The capacitor should now pull free of the terminal strip or printed board.
How do you make light with a battery?
you have to have 2 wires. then you put a wire to the positive side of the battery(+) and the other wire to the negative side of the battery(-). then both other ends to the light bulb one end to the side and one end to the bottom. you have to have 2 wires. then you put a wire to the positive side of the battery(+) and the other wire to the negative side of the battery(-). then both other ends to the light bulb one end to the side and one end to the bottom.
How does a wire connect to a bulb?
A wire connects to a bulb by attaching one end of the wire to the metal base of the bulb and the other end to the metal contact on the bulb socket. When the circuit is complete, electricity flows through the wire and powers the bulb, causing it to light up.
Connecting an AC adapter to a MP3 player as if it is a battery .. would it work?
Yes, you can cut the end connector of the adapter and peel the 2 wires. The white wire is the positive and the black one is the negative, then open the battery place of the MP3, remove the battery and hook the negative wire to the spring and stick the positive wire to the other end. Adjust your adapter to 1.5V and run your MP3 player :)
How do I create an electro magnet?
It is easy to make an electromagnet if you have a battery, some copper wire and a nail. Just wrap the copper wire neatly and tightly (all in one direction) around the nail making sure to leave extra wire at each end of the nail to connect to the battery. The more wire you wrap, the stronger the battery will be. Attach the one end of the wire to the positive end of the battery and the other to the negative end. You have now created an electromagnet!

Is there a direction of current with an Axial Capacitor?
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
