Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's law is represented by the equation V=IR, where V is voltage, I is current, and R is resistance.

• It is used to calculate the current flowing through a circuit given the voltage and resistance.

• The law is named after Georg Simon Ohm, a German physicist.

• The law is applicable to both AC and DC circuits.

• Strength: Strong analytical skills - I successfully led a project that reduced costs by 20% through efficient resource allocation.

• Strength: Excellent communication - I foster collaboration among team members, ensuring everyone is aligned with project goals.

• Weakness: Difficulty in delegation - I tend to take on too much myself, which can lead to burnout; I'm working on trusting ...read more

Flash point is the lowest temperature at which vapors ignite; fire point is the temperature at which sustained combustion occurs.

• Flash point is crucial for assessing flammability of liquids.

• Fire point is typically a few degrees higher than the flash point.

• Example: Gasoline has a flash point of around -45°C, while its fire point is about -40°C.

• Used in safety regulations and material handling guidelines.

LEL and UEL of natural gas indicate the flammability range, crucial for safety in handling and usage.

• LEL (Lower Explosive Limit) of natural gas is approximately 5% by volume in air.

• UEL (Upper Explosive Limit) of natural gas is about 15% by volume in air.

• Concentration below LEL means the mixture is too lean to ignite.

• Concentration above UEL means the mixture is too rich to ignite.

• Example: A natural gas leak with 6% concentration is flammable, while 4% is not.

Syphon effect is the flow of liquid from a higher level to a lower level through a tube due to atmospheric pressure.

• It occurs due to the difference in pressure between the two ends of the tube.

• The liquid flows from the higher level to the lower level until the pressure is equalized.

• It is commonly used in aquariums, toilets, and irrigation systems.

• The syphon effect can also be used to transfer liquids from one container to another without the need for a pump.
