How the direction can change of Permanent split capacitor motor?
A single speed permanent split capacitor AC induction motor has two separate pairs of series wound stator windings arranged at right angles to each other around the central rotor. The main run winding is connected directly to the AC power source while the secondary start winding is connected to the same source with a capacitor in series with it. The capacitor causes an electrical phase shift to the power in the start winding relative to the run winding, to produce a rotating magnetic field around the rotor which can start it turning. Since the capacitor remains in the circuit while the motor is running it's called a permanent split capacitor design.
Do capacitors have internal resistance?
1. The capacitor has Lead resistance in series with the capacitor2. Since most capacitor use Dielectric and they have a leakage resistance and it is parallel to the Ideal Capacitor.
Why inductor use in series capacitor in parallel?
That depends on the type of circuit you are talking about. Sometimes both an inductor and capacitor are both in parallel with each other. This is called a tank circuit. Sometimes they are both used in series. These are both examples of resonant circuits. Sometimes the inductor can be in parallel with an applied voltage and the capacitor in series. This is a form of high pass filter. On the other hand, the inductor can be in series and the capacitor in parallel to for a low pass filter.
What is the most resistance that can be in series with the capacitor if the capacitor is to charge to at least 88 percent of its final voltage in no more than 8.0 s?
Without knowing the capacitance of the capacitor, your question cannot be answered.
What is the time constant of a 0.001 microfarad capacitor and a 15000 ohm resistor connected in series in a dc circuit?
The same as the time constant of a 2.7 microfarad capacitor and a 33 ohm resistor connected in series.
How introduction of a die-electric increases the capacitance of the capacitor?
By connecting a capacitor in series the total dielectric thickness between the positive and negative terminals of the source, since you double dielectric thickness has effectively doubled, the total capacitance is one half of either capacitors.
Can the capacitor be inserted in series in order to improve the power factor?
In a circut we use capacitor in series for improving power factor
IN case of lossy capacitor what effect would be on series equivalent resistor?
In case of a lossy capacitor, its series equivalent resistance will be large.
What is the solution for overcoming the disadvantage of series capacitor?
Your question is unclear; why do you think that there is a disadvantage in having a series capacitor? And what sort of circuit are you referring to?
What happen if coil and capacitor are connected in series?
series resonant circuit

The effect of resistance on the rate of charging or discharging a capacitor?
If the resistance is in series with the capacitor, the charge/discharge time is extended.
How does connecting batteries in series affect the overall voltage output?
Connecting batteries in series increases the overall voltage output.
Do capacitors have internal resistance?

Is the start capacitor connected in series with the start winding?
yes
