what are those factors that get affected by a capacitor if we use it in a circuit?

Question

capacitors are oftenally used in many types of circuits and obviously its use in the circuit is just not for charging and discharging so what other factors of a circuit that get affected by the capacitors

Answer 1

-Power factor correction (the capacator is chariging during the half cycle that the inductor of a motor coil is discharging).



-Filtering



-Smoothing out a rectfied waveform



-As a timer, since it rate of charging is easily calculated



-Slowing down a pulse

Answer 2

The time constant of the circuit gets affected. In the case of AC circuits, the power factor gets affected, generally it improves. The frequency of a circuit with R, L and C depends on all the three factors.

Answer 3

Capacitors affect the circuit by charging and discharging.

As filters in series they block DC but pass AC; in parallel they pass DC and short out AC.

Charging and discharging a cap through a series resistance takes time so the RC time constant can be used in timing circuits.

Answer 4

Power factor is affected by capacitance. Like power factor is affected by inductance. The difference is Inductance causes current to lag the voltage by 90 degrees were as capacitance causes the voltage to lag the current by 90 degrees. If a factory or house has many inductive loads (motors, large mainframes) the power factor will be way off and could be penalized by the utility because they charge for wattage not voltage. To correct this banks of capacitors can be added to balance the power factor back to 1 inversely you can add inductance on large capacitive loads as well to bring your power factor back into parameters...
