HERE THE NOTES :-

(A) CAPACITOR DEFINITION:

(A) A capacitor is an electrical component that stores and releases electrical energy in a circuit. It consists of two conductive plates separated by an insulating material (dielectric). Capacitors are used for energy storage, filtering, and signal processing in various electronic and electrical applications. They are measured in farads (F).

(B) WHY CAPACITOR IS USED:-

(A) A capacitor is used in a ceiling fan to help start and run the motor efficiently. It serves two main purposes:

1. Starting the Fan – The capacitor creates a phase shift in the current, generating a rotating magnetic field that helps start the fan motor.
2. Smooth Running – It ensures continuous and stable rotation by improving the motor's efficiency and torque.
Without a capacitor, the fan may not start or run at a lower speed with reduced efficiency.

(C) WHY IS MFD IN A CAPACITOR:-

(A) MFD in a capacitor stands for Microfarad (µF), which is a unit of capacitance.
1 MFD (µF) = 1 × 10⁻⁶ Farads (F)
It indicates the capacitor’s ability to store electrical charge.
Common in ceiling fans, motors, and power circuits, where capacitors are rated in µF (e.g., 2.5 µF, 5 µF, 10 µF).

(D) WHY WE USE 2.5 MFD IN CAPACITOR?

(A) The 2.5 MFD (µF) capacitor is commonly used in ceiling fans because it provides the optimal phase shift needed to start and run the fan motor efficiently. Here’s why:
1. Proper Phase Shift for Motor Starting
A ceiling fan motor is usually a single-phase induction motor, which needs a capacitor to create a rotating magnetic field for starting.
A 2.5 µF capacitor provides the right phase shift (usually around 90°) to ensure smooth starting and operation.
2. Correct Speed and Efficiency
Using a higher capacitance (e.g., 4 µF or 5 µF) may increase speed but can overload the motor and cause overheating.
Using a lower capacitance (e.g., 1 µF) may cause starting issues or slower speed.
3. Standard Design in Fan Motors
Most ceiling fans are designed to work with a 2.5 µF capacitor to balance performance, power consumption, and lifespan.
Manufacturers test and optimize motor windings to work best with this capacitance.
4. Power Factor and Stability
A 2.5 µF capacitor helps improve the power factor and reduces electrical losses in household circuits.

(E) WHAT IS 440 VAC IN CAPACITOR:-

(A) 440 VAC in a capacitor refers to the **maximum voltage the capacitor can safely handle in an AC circuit. Here’s what it means:
1. Voltage Rating (VAC) Explanation
"440 VAC" means the capacitor can handle up to 440 volts of alternating current (AC) without breaking down or failing.
If the voltage exceeds 440V, the capacitor may overheat, degrade, or even explode.

(F) WHAT IS MPP SH 25/85 and 2/22 TERMS IN A CAPACITOR:-

(A) The notation "MPP SH - 25/85, 2/22"on a capacitor provides specific information about its construction, temperature ratings, and humidity tolerance. Here's a breakdown:
1. MPP SH:
Metallized Polypropylene (MPP): Indicates the capacitor uses a metallized polypropylene film as its dielectric material, known for low loss and high stability.
Self-Healing (SH): Refers to the capacitor's ability to repair itself after dielectric breakdowns, enhancing longevity and reliability.
2. 25/85:
Temperature Range:Specifies the capacitor's operational temperature range.
25: Represents the lower category temperature, typically -25°C.
85: Represents the upper category temperature, typically +85°C.
This means the capacitor is designed to function effectively between -25°C and +85°C.
3. 2/22:
Humidity Endurance: Indicates the capacitor's ability to withstand humid conditions.
2: Represents the number of days the capacitor can endure high humidity.
22:Represents the relative humidity percentage.

Thus, "2/22" suggests the capacitor can withstand *2 days at 22% relative humidity* without significant performance degradation.
