For physical size-yes, if voltage rating is the same or more.
For capacitance size-it depends on where the cap is used. In an audio circuit, it may affect frequency response or distortion.
The electrolytic capacitor should be connected in only one direction.
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.
For analog application that need swinging signal from positive to negative that will not work for you. But for DC applications where signal is always positive (or negative) that will be ok to exchange the capacitors with no harm to your circuit. Hope that will help you, if you need to find good quality electronic components i advise you to check www tmartis com, you can find a lot of good stuff there.
Charge the capacitor. Potential difference is a scientific term for what is more commonly called voltage. ANSWER: If big enough the battery will see a short initially and then proceed to charge the capacitor at a rate of 63% of the voltage in one time constant defined as RC For engineering purposes after 5 time the time constant the battery will and the capacitor zero potential different. The proper term should be virtual no difference.
You can get away with a 30% or so larger capacitor.
a sea producer is a plant that lives under the sea a on land producer starts of a food web of creatures as it is eaten and it eats no animal so a sea producer would start an under sea food web
To repair a 680 microfarad capacitor, buy a new one and install it in place of the old one. It is unrealistic to attempt repair of a capacitor.
No, the value is far too small. If it is the capacitor used for the timing, the time/s will be reduced to one tenth of the deisred value.
if your small get a small one and if your big get a big one
Fill the big bucket. Use that to fill the small one. Now you have 2 in the big, and the small is full. Pour out the small one. Pour the 2 quarts from the big one into the small one, fill the big one, and then use 1 quart from the big one to fill the small one. Now you have 4 quarts in the big one. ■
Sometimes. The exception is when the capacitor is used as a "timing" device. But 7.5 mfd and 5 mfd are so large that one would guess that they are not being used as timing devices.

A big one
A big one
One is big. One is Small.
umm... i guess both if your big a big and small small one dork
Yes, the size of a capacitor "matters" just as much as the size of a resistor "matters". In both a capacitor and a resistor "size" refers not only to the electrical value of the item but to its current-carrying capacity: a small resistor will burn up if you try to push too much current through it. A big resistor will be able to carry a much higher current than a small one having the same resistance value.Similarly, a small capacitor will be destroyed if you try to push too much current through it and a big capacitor will be able to carry a much higher current than a small one, even if both have exactly the same capacitance value. Capacitance values are measured in Farads (F), microFarads (uF) and picoFarads (pF). Just as a resistor has "Resistance " measured in Ohms, a capacitor has "Capacitive Reactance" or "Impedance", measured in Ohms.The Impedance of a capacitor varies with the frequency of the alternating current passing through it. (This is quite different behavior to a resistor: the Resistance of a resistor does not change with the frequency.) If you look in a book about electrical engineering components you will be able to learn how the Capacitive Impedance is calculated according to the frequency. "The impedance of a capacitor is inversely proportional to the frequency - that is, for very high-frequency alternating currents the reactance approaches zero - so that a capacitor is nearly a short circuit to a very high frequency AC source. Conversely, for very low frequency alternating currents, the reactance increases without bound so that a capacitor is nearly an open circuit to a very low frequency AC source. This frequency-dependent behaviour accounts for most uses of the capacitor." [From Answers.com]
