For power factor improvement so that the KVA demand is reduced.
Capacitors are used in most fluorescent lamp circuits, regardless of how many tubes are used.
A tube light uses a condenser which is the old term for a capacitor. It functions as a small battery in a circuit.
An oil filled capacitor is used in (PSC) motor because the capacitor is in the circuit the whole time the machine is running. The capacitor is oil filled to cool it due to being in circuit the whole time
because without using capacitor or resistor in a circuit,it cant be complete.Resistor is used to protect the circuit by giving a certain amount of voltage.Capacitor is used to charge and discharge purpose.

A tube light uses a condenser which is the old term for a capacitor. It functions as a small battery in a circuit.
The small cylindrical thing that You see (generally on a side of the choke coil) is the "starter " of the tube light. This is the capacitor used in tube light. And is used to provide a momentary voltage rise of nearly 400V to start up the tube light hence Starter.
Starters in tube light uses capacitors to produce a momentary high voltage of 400V due to discharging of capacitor. This momentary high voltage will start the gaseous discharge to priduce light by initial flickering . now,if capacitor is not used , the power supply from the main cannot start the gaseous discharge .
An oil filled capacitor is used in (PSC) motor because the capacitor is in the circuit the whole time the machine is running. The capacitor is oil filled to cool it due to being in circuit the whole time
Capacitor is used in biasing circuits to block the passage of DC signals.

same as any other capacitor. however they are usually used where higher voltages are.
Phase difference.
On the contrary, capacitors ARE used in a.c. circuits.
To smooth the output of the pulsating DC.
