Capacitive reactance is an opposition to changes in voltage across an element. This resistance is usually caused by a magnetic field.

What effect does the series resistance of a capacitor used in a capacitor filter have on diode current and ripple voltage compared with an ideal capacitor of no resistance?

The effective resistance of the capacitor reduces the ripple current through the capacitor making it less effective in its function of smoothing the voltage. But if the capacitor filter is fed by a transformer and diodes, the resistance of the transformer exceeds that of the capacitor.


Regarding Capacitors- can any general capacitor work on a circuit diagram that shows a polarized capacitor or do you need a special capacitor for polarization?

A Polarized capacitor means that the capacitor is polarity sensitive. if you were to connect the capacitor incorrectly the capacitor would blow up. A capacitor that is marked as being polarity sensitive will have the negative lead labeled usually with a white strip. These capacitors can only be used in conjunction with a dc source. Always consult a professional when installing electrical equipment.


What happen to the energy stored in the capacitor while the capacitor is discharging?

It flows out of the capacitor into the external circuit


How one can know that what kind of capacitor to use in circuit?

paper capacitor


Can I check the capacitor value by using analog or multimeter?

You can see if the capacitor charges and discharges with an ohmmeter. You can check the value of the capacitor if the multimeter has the facility. With an ESR meter you can establish the value of the capacitor while in circuit.

Why is the theoretical yield of a reaction determined only by the amount of the limiting reactant?

The theoretical yield of a reaction is determined by the limiting reactant because this reactant is completely consumed in the reaction, and the amount of product that can be formed is limited by the amount of the limiting reactant available. Any excess of the other reactant does not contribute to the formation of additional product beyond what is possible with the limiting reactant.


Which reactant in the reaction of sodium carbonate and calcium chloride dihydrate is the limiting reactant if 1.00 gram of each reagent is used?

To determine the limiting reactant, calculate the moles of each reactant using their molar masses. Then, use the stoichiometry of the reaction to determine which reactant will be consumed first. Whichever reactant produces the lesser amount of product will be the limiting reactant.


What is the difference between a limiting reactant and an excess reactant?

the limiting reactant is how much of a compound or solution you need to make an experiment possible. the excess reactant is the amount left over from the other compound or solution used (the other reactant that is used)
