The electrolytic capacitor should be connected in only one direction.
The electrolytic capacitor can only have voltage across it in one direction. Failure to comply will result in catastrophic destruction of the capacitor.
You can test a capacitor using a multimeter and two leads by placing the multimeter in ohms mode. It works best with a needle type meter, not a digital meter. Connect the leads to the capacitor and you will notice that the resistance pulses down, and then settles out at infinity. Reverse the leads, and you will notice the same effect, except that the pulse will be larger because the capacitor got charged in the opposite direction. Go back and forth. This won't be apparent for very small capacitors because the pulse is too short. Also, for electrolytic capacitors, they should only be charged in one direction, so you should start by discharging the capacitor and then connecting it in only one direction. Do not reverse the leads in this case. Just discharge and try again to see the effect. Try this for various capacitors. You will notice that the pulse duration is larger for larger capacitance.
Bypass capacitors are used to bypass (shunt) unwanted signals to the ground. A common use is in power supplies where a bypass capacitor is connected in parallel with the main filter capacitor to shunt noise and other high frequency interference to ground which the main capacitor may not be able to do.
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.
leaning in one direction or another
That would be done by a resistor connected between the two plates.
the capacitor has 2 wires or poles, one is the ground or negative and the other one is the hot or positive... if it is for car audio amp the ground is connected to the chassis and the positive is connected to the battery and to the positive wire of the amp.

The units of capacitance are called farads. A one farad capacitor is a capacitor with 1 volt potential difference with 1 coulomb of charge on the capacitor, C = Q/V or Q=CV So the charge held on your capacitor is Q = CV = 9Volts * 0.40*10-6Farads=3.6*10-6 Coulombs
Oh it depends... 4 wires? One Direction: BLK RED BLU WHT Going the wrong way then: RED WHT BLK BLU
When a charged capacitor is connected to an uncharged capacitor charge flows from the charged to the uncharged capacitor until there is no net force on the charge carriers. This means that both capacitors are at the same potential, because if they were not, there would be an electric fieldand hence a force on the charge carriers of magnitudeand the charge carriers would move to equalize the potentials and reduce the electric field and hence the force, eventually to zero. Of course, as charge flows from one capacitor to the other, the total charge is conserved. In the diagram above, when switch is closed chraged flows from the top capacitor to the bottom. When charge has stopped flowing, Also, because the potentials are equal(1) Suppose then that the capacitor at top left is initially charged to potential ofand that it has capacitanceand is then connected to a capacitance Initiallystores a charge Then (3) From (1) (4) Sub (4) into (1) to get Now usefor either capacitor to findUsing it for (2) gives from A Level Physics Notes
They should be facing in the direction of the book.
The direction of the motor is dependent on the way the stator coils are wound.
there is no separate capacitors for AC and DC. All capacitors are same. Electrolytic capacitors are manufactured by creating a die-electric by chemical etching or electroplating on one plate. Such capacitors when connected in AC circuit dislodges the die-electric material and thus results in short circuit between the two parallel plates of the capacitor. For AC circuits only non-electrolytic capacitors should be used. The common type is oil impregnated paper capacitor.
A capacitor could be two parallel plates close together but unconnected, and then the plates are connected to either side of a battery. Current flowing causes charge to build up on the plates, positive on one plate and negative on the other, until the voltage across the capacitor is equal to the battery voltage. The amount of charge that has flowed in, divided by the voltage, is called the capacitance, measured in Farads.If the battery was one volt, and the charge was one coulomb (i.e. one amp for one second), then the capacitor has a capacitance of one Farad.Usually capacitors are measured in microfarads or picofarads.
