Polar capacitors are acidic wet dielectric type capacitors which work only when there is a DC voltage present between its two leads in right polarity. Polar capacitors are ideally suited for a DC power supply ripple filter. When connected in wrong polarity, chemical reactions within a polar capacitor can cause them to blow up, often violently, causing injury to someone nearby. Most polar capacitors these days come with a safety valve to release internal pressure build up.
Non polar capacitors are usually dry types made of ceramic, mylar, polyester or any possible dry insulator as a dielectric. Two polar capacitors connected back to back also make a non-polar capacitor. They work well in all situations whether there is any DC voltage present between their leads or not. Non polar capacitors are often very large and impractical in most applications except where a small capacitance value is required.
Some good applications for non-polar capacitors are: an AC motor starter, an AC line spike filter and a crossover network. Since voltages across an AC motor or inside a speaker system consist only of pure AC, polar capacitors cannot be used in those cases.
Polarized capacitors are typically large devices known as electrolytic or tantalum type packages, used for filtering or stabilizing voltage sources, usually in DC type circuits. Construction of these is if I recall correctly, an aluminum foil called the anode (positive lead), separated by an oxide film with a dielectric material known as the cathode (negative lead), hence polarity.
Non-polarized are similar to polarized except the plates are similar metal.
Polarized caps are typically used in large voltage situations, such as DC line filtering to reduce noise related to uneven voltage levels after rectification from an AC source. Mainly measured in microfarads. Polarity is critical to these devices. They are marked with the voltage rating (usually double the circuit voltage used) as well as the farad marking.
non-polarized caps are typically used in low voltage situations, both AC and DC. Polarity is not critical. Measured in pico farads typically.

the positive end of one molecule attracts the mobile electrons of the nearby non polar molecule in this way polarity is induced these forces called as dipole-induce dipole forces

Inverters can be made in many different ways. You can use CMOS transistors. Having a p-fet transistor pulled high and a n-fet transistor pulling low. Both gates are connected together as inputs. Output is the node between the n-fet and p-fet. The other way is using CML (Current Mode Logic) which uses Bi-polar transistors. Its design rather steers current. Hard to explain the physical layout but you should be able to google "inverter cml". CML is much more robust, drives better, and it is faster.
Polar capacitor used in those places where the voltage will never switch polarity on them under proper use conditions. Their high capacitance means they can be used more effectively for power supply filtering, reducing ripple in a rectifier, and softening on/off switching.
Bi = two Polar = poles So bipolar means fluctuating between two poles
Uni-polar neurons, also known as unipolar neurons, have a single process that extends from the cell body, which then branches into two parts: one functioning as a dendrite and the other as an axon. In contrast, bipolar neurons possess two distinct processes: one dendrite and one axon, which are both attached to the cell body. Uni-polar neurons are primarily found in sensory pathways, while bipolar neurons are typically involved in sensory functions, such as in the retina of the eye. This structural difference reflects their distinct roles in the nervous system.
Monopolar cells have a single process extending from the cell body, while bipolar cells have two processes. Multipolar cells have multiple processes extending from the cell body. This structural difference can impact how these cells transmit signals within the nervous system.
The bond would be considered polar if the electronegativity difference between the two atoms is 0.5. This is because a difference in electronegativity values between 0.5 and 1.7 indicates a polar covalent bond.
The root word for bipolar disorder is "bi-" meaning two, and "polar" referring to opposite extremes. This reflects the characteristic swings between the two poles of mania and depression in individuals with this disorder.
paper capacitors are non polar, so they have the same symbol as any other non polar capacitors like ceramic disc, two parallel lines.
the polar one is less stable than the non-polar one

Polar covalent. There is a significant difference in electronegativity between C and F.
Polar covalent. There is a significant difference in electronegativity between C and F.
Bonds between two nonmetals that differ in electronegativity (EN) are usually polar. Electronegativity is the tendency of an atom to attract electrons. Nonmetals with EN differences of 0.5-1.6 form polar covalent bonds. The greater the difference, the more polar. If the EN difference is
HBF2 is polar. This is because the bond between hydrogen and fluorine creates a dipole moment due to the electronegativity difference between the two elements.
